When you throw a ball upward what happens to its speed while it is going up? ›

Answer: When we throw a ball upwards, its speed retards gradually. This is because the earth produces a gravitational force which brings down everything that goes up. So when a ball is thrown upward the gravity applies force to bring it down which decreases its speed of going up.

When you throw a ball directly upward what is true about its acceleration? ›

When you throw a ball up in the air, its speed decreases, until it momentarily stops at the very top of the ball's motion. Its acceleration is −9.8 ms−2 at the very top since the body is moving upward against the gravity. In other words, the acceleration due to gravity g=9.8 ms−2↓.

What force was exerted on the ball 1 second after it was thrown? ›

Answer. Once you release the ball, you are not applying a force to it; it is freely falling (despite its upward motion). The only force acting on it is the gravitational force, pulling it downwards (which is why it slows down and stops momentarily at the apex, before coming back down).

What is the velocity and acceleration of a ball thrown straight up? ›

Therefore, velocity at the top is zero and acceleration is acceleration due to gravity (g). Was this answer helpful?

When a ball is thrown upward What is the energy? ›

When a ball is thrown upward, kinetic energy keeps on decreasing whereas potential energy keeps on increasing but the total energy of the ball will remain the same. The velocity is zero when the ball reaches maximum height. Hence no kinetic energy but only potential energy exist.

When a ball is thrown upward by how much does the speed decrease each second? ›

Reasoning: At the top, its speed must go to zero. But acceleration (i.e.change of speed in every second) is 10 m/s/s. Thus its speed decreases by 10 m/s every second. Since it started with 10 m/s, it will take 1 second for its speed to go to zero and reach the top.

What happens when an object is thrown upward? ›

Gravitational force of the earth acts on every object having mass. When an object is thrown upwards the gravitational force of the earth acts against the velocity of the object and pulls the object downwards, i.e, towards itself. thus the object returns back towards the earth.

When a ball is thrown upward its acceleration is positive or negative? ›

The acceleration due to gravity is downwards towards the surface of the earth. Hence in this case the downward is considered as positive and the upward is considered as negative. Since the acceleration moves the ball up against the force of gravity, it is negative.

When an object is thrown upwards is the acceleration positive or negative? ›

If an object is thrown in upward direction, then the gravitational acceleration is positive.

What is the acceleration of a body thrown upward? ›

Once the body is thrown with an initial velocity , the vertical component of the initial velocity will only experience retardation (negative acceleration ) = -9.8 m/sec/sec. The horizontal component of the initial velocity will remail constant.

What is the acceleration of body that is thrown vertically upwards? ›

Initial velocity = u. Acceleration of the body (a) = - g. At maximum height, final velocity () = 0. At maximum height, the velocity of the body will be zero. As the acceleration due to gravity is always in a downward direction and the body is thrown in an upward direction.

Does throwing a ball down increase acceleration? ›

When an object is thrown downwards, the only things that change are its initial velocity, initial kinetic energy, and initial momentum; as compared to dropping it. None of these quantities affect the acceleration due to gravity felt by an object. Hence, the acceleration would still remain g = 9.8 m / s 2 (downwards).

What is the acceleration when a ball is thrown upward from a bridge? ›

Now talking about the acceleration, in all such motion where a ball is thrown upwards the acceleration is always g(gravitational pull) =9.8m/s^2.
