Why does a ball thrown vertically upwards in a?

Solution. The reason is that when the ball is thrown, the ball is in motion along with the person and train. Due to the inertia of motion, during the time the ball remains in air, the person and ball move ahead by the same distance. This makes the ball fall back into the thrower's hand.

Why does a ball thrown vertically upwards in a moving train come back?

Due to inertia of motion, as long as the ball stays in air, both the person and the ball move in the same direction which cause the ball to fall back to the thrower's hand.

Why does the ball come right back in hand when thrown upwards in a moving train and behave as if the train is at rest?

The reason is that at the moment the ball was thrown, the ball was in motion along with the person and the train, due to the inertia of motion. So during the time ball remains in air, both the person and the ball move ahead by the same distance. This makes the ball to come back to his hand on its return.

When a ball A is thrown vertically upward?

When a ball is thrown vertically upwards, it goes through a distance of 19.6 m. Find the initial velocity of the ball and the time taken by it to rise to the highest point. (Acceleration due to gravity, g=9.8 ms−2) [3 MARKS]

When a ball is thrown vertically upwards at maximum height?

At maximum height, the ball is momentarily at rest as it changes its direction of motion before accelerating towards the surface of earth. Hence at maximum height the magnitude of velocity is zero and acceleration is same as the acceleration due to gravity ie. 9.8 m/s^2.

When a ball is thrown vertically upwards the gravitational potential energy of the ball Dash?

PE= m×g×h, which shows that potential energy is directly proportional to height, hence as height increases, potential energy increases.

When a ball is thrown vertically upwards it reaches a maximum height of 5m the initial velocity of the ball was?

Thus the initial velocity of the ball is 9.9 m/s.

When a ball is thrown vertically upwards why does its velocity decrease?

According to the law of conservation of energy its kinetic energy is getting converted in to potential energy because of gain in height. So, if the velocity of a ball goes on decreasing when it is thrown vertically upwards. When its velocity becomes zero, its potential energy becomes maximum.

When a ball is thrown up vertically with velocity?

When a ball is thrown vertically upwards with velocity v0, it reaches a maximum height of h. If one wishes to triple the maximum height then the ball should be thrown with velocity.

When a ball is thrown vertically upwards with a velocity v not the total time taken to return to the point of projection is?

∴ Total time taken by ball to return to the surface, T=2t=10 s.

Why does a ball thrown into the air tend to fall back to the ground?

Gravitational force is the attractive force exerted by the earth on all the objects in the universe. Example of gravitational force is when a ball is thrown upwards, it falls back on the ground because of gravitational force.

What happens if you throw a ball in a moving train?

Assuming that the ball and the throw are the same, the ball will land at the same distance from the thrower. As you mentioned yourself, there is no difference between a motionless train and one that is moving at constant speed (Galilean relativity).

What happens when we throw a ball in a train?

So it will follow a projectile motion when looked from the ground frame. So though it looks like a vertical motion to the person throwing the ball in the train, it's a projectile motion to the person on the ground with the range of the projectile equal to the distance covered by the train in the same time.

When a train suddenly moves forward the passengers fall backward is an example of?

Law of inertia states that an object remains in a state of rest or of uniform motion in a straight path unless forced to change that state by an applied force. so, the passengers are in rest when train moves suddenly then the state of rest break by applied force.

When a coin is tossed in moving train?

During uniform motion of the train, when the coin is tossed, the coin goes up with initial speed of the train. Hence, because of inertia of motion, the coin travels the equal distance as the train and will fall in the hands of the boy. Accelerated motion is a type of motion in which speed of the body increases.

When an object is thrown vertically upward the force of gravity?

Force of gravity always act toward the center of the earth , so when an object is thrown up,the force of gravity will act in opposite direction of motion,that's toward the center of earth.

When a ball is thrown up vertically with a velocity Vo it reaches a height h'if one wishes to triple the maximum height then the ball should be thrown with a velocity?

To triple maximum height, i.e. 3H, we have, 3H=2gu′2 or u′2=3u2 or, u′=3 u.

When a ball is thrown vertically upwards through the distance of 19.6 meters where is the initial velocity of the ball taken by it to rise to the highest point?

Thus the acceleration in the ball is negative which means that the value of g is to used here with the neagtive sign. Thus ,the intial velocity of the ball is 19.6 m/s which means that the ball has been thrown upwards with a velocity of 19.6 m/s .

When a ball is thrown vertically upwards its mechanical energy?

When a ball is thrown vertically upwards, the kinetic energy of the ball converted into potential energy of the ball. But the total energy of the ball remains constant during its motion. So option 1 is correct. It is because at the beginning the ball has high kinetic energy and no potential energy.

When a ball is thrown vertically upwards its velocity keeps on decreasing what happens to its kinetic energy when it reaches the maximum height 1 point?

Solution. When a body is thrown vertically upwards against the force of gravity, its kinetic energy keeps on decreasing as its velocity decreases. At the maximum height, kinetic energy becomes zero, as the velocity of the body becomes zero at this moment.

Does the speed of ball thrown vertically upwards increase or decrease which force is responsible for it?

At the highest point of rise its vertical velocity is zero. The reason why it is decreasing is the downward gravitational force acting on it at any instant it is rising. This downward force is responsible for the negative acceleration which is -9.8 m/s^2.

When a ball is thrown vertically upward direction then which of the following remains constant?

When a ball is thrown upward, its acceleration always remains constant which is equal to the acceleration due to gravity.

How does the kinetic energy of an object varies when it is thrown vertically upwards?

When an object is thrown vertically upwards then energy conversion takes place ( According to law of conservation of energy). At earth surface the object has highest kinetic energy but when the body reaches at highest point the kinetic energy becomes zero and the object acquires highest potential energy.

Does a ball take longer to go up or down?

The answer is: Down.

Only if there was no air resistance would the up and down times be the same.
