What happens to a velocity when the acceleration changes?
If the acceleration changes, the velocity of an object will also change. If the acceleration increases, the velocity will increase. If the acceleration decreases, the velocity will decrease. The velocity and acceleration of an object are directly related.
An object has initial velocity in the upward direction a final velocity in the downward direction and undergoes constant acceleration What can you say about its average acceleration?
The average acceleration of the object will be negative since it changes direction from upward to downward velocity. The acceleration will be constant because the object undergoes constant acceleration throughout the motion.
Describe how the velocity and acceleration of an object change as it fell from tall building?
The magnitude of the velocity will increase. The velocity will be downward - and since it increases, the acceleration will be downward. The acceleration doesn't change (it will remain constant at about 9.8 m/sec2), unless air resistance becomes significant.
What is acceleration at instantaneous maximum velocity?
In the case of an object thrown, batted, teed off, or dropped, its acceleration at the instant of its maximum velocity is 9.8 meters per second2 downward.
When a falling object has reached its teminal velocity its accleration?
When a falling object reaches its terminal velocity, its acceleration becomes zero. The downward force of gravity is balanced by the upward force of air resistance, resulting in no overall acceleration.

What happens to an object when it undergoes acceleration is it the speed or velocity that increases?
When an object undergoes acceleration, it is the velocity that increases. Acceleration is the rate of change of velocity, so an object experiencing acceleration will have its velocity change over time, either by speeding up, slowing down, or changing direction.

If an object moves with constant acceleration what happens to the velocity?
The velocity increases at a constant rate.
What is acceleration at instantaneous maximum velocity?
In the case of an object thrown, batted, teed off, or dropped, its acceleration at the instant of its maximum velocity is 9.8 meters per second2 downward.

When a falling object reaches its terminal velocity, its acceleration becomes zero. The downward force of gravity is balanced by the upward force of air resistance, resulting in no overall acceleration.
If the acceleration of an object is in the same direction as the velocity what happens to the velocity of the object?
a = F/m, where a is acceleration, F is net force, and m is mass in kilograms.
What happens to an object's velocity when it accelerates?
"Acceleration" implies that the velocity changes.
Is the acceleration due to gravity always pointing vertically downward even for an object whose velocity is vertically upward?
Yes, the acceleration due to gravity always points vertically downward, regardless of the direction of an object's velocity. This is because gravity is a force that attracts objects towards the center of the Earth.
Is it possible for an object with constant negative acceleration to change the direction in which it is moving?
Sure. Anything you toss with your hand has constant acceleration after you toss it ... the acceleration of gravity, directed downward. If you toss it upward, it starts out with upward velocity, which reverses and eventually becomes downward velocity.
An object is falling at its what if it falls at a constant velocity?
If an object is falling at a constant velocity, then the net force acting on it is zero. This means that the force of gravity pulling the object downward is balanced by an equal and opposite force. The object will continue to fall at a steady speed without accelerating.
