What happens to the velocity and acceleration of a ball if it is dropped straight down?

The ball has zero velocity, but the acceleration due to gravity accelerates the ball downward at a rate of –9.8 m/s2. So the final velocity is 9.8 meters/second directed straight downward. The magnitude of this velocity — that is, the speed of the ball — is 9.8 meters/second.

What happens to velocity when an object slows down?

According to our principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus, this object has a negative acceleration. In Example D, the object is moving in the negative direction (i.e., has a negative velocity) and is speeding up.

When we throw a ball upward what happens to its speed?

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 a ball is thrown upward its momentum first decreases and then increases?

When a ball is thrown upwards, its momentum first decreases and then increases. Is conservation of linear momentum violated in this process? No, the momentum conservation principle is not violated. Infact, this principle cannot be applied to this case as external force due to gravity is involved.

What happens to the velocity of the ball when it falls?

When you toss the ball into the air, you impart an initial velocity which slows down due to the acceleration of gravity until that initial velocity is reduced to zero, then the ball starts falling. It accelerates the same throughout.

What happens to the velocity when you throw an object downward?

When you throw or project an object downward, it is accelerated until it is released at some velocity. If you know this initial velocity, there are simple derived equations that allow you to calculate the velocity when the object reaches a given displacement from the starting point or when it reaches a given elapsed time.

Is it possible to drop a ball with a negative acceleration?

Granted it remains firmly in negative numbers, (the velocity is still decreasing) BUT it is possible to drop a ball in a way so that the acceleration of the ball rises as it falls. But lets return to the part before it drops, the velocity is obvious, it increases quite rapidly, but what about acceleration?

How does gravity affect a volleyball throw?

Gravity is constantly pulling the mass of the ball towards the mass of the ball, but you are stopping it by holding it in your hand. Then you allow let it help you pull the ball down a little as you reach back, getting the ball back and down as you wind up for the throw.
