Acceleration is the change in velocity of an object over time. Take note that velocity is a vector quantity which means that it has magnitude and direction...
Thus...
An object undergoes acceleration when:
1. there is a change in the magnitude of the velocity (speed) of an object.
2. there is a change in direction of an object.
3. it changes both in direction and magnitude.
An object undergoes acceleration when there is a change in its speed, direction, or both. For example, when a car speeds up, slows down, makes a turn, or changes direction, it is experiencing acceleration. Acceleration is the rate of change of velocity with respect to time.

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.
How does air resistance affect the acceleration of a falling object-How does air resistance affect the acceleration of a falling object?
It reduces the acceleration of the falling object due to friction.
Can a stationary object have a non zero angular acceleration?
No, a stationary object cannot have a non zero angular acceleration. Angular acceleration is a measure of how an object's angular velocity changes over time, so if an object is not rotating, its angular acceleration is zero.
What is and acceleration force divided by mass?
Acceleration force divided by mass gives you the acceleration of an object. This is a measure of how quickly the object's velocity is changing over time.
How does net force affect acceleration?
The net force acting on an object is directly proportional to its acceleration, according to Newton's second law of motion. When the net force increases, the acceleration of the object increases as well. Conversely, when the net force decreases, the acceleration of the object decreases.
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.
When an object undergoes an acceleration?
when it is acted on by a force
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.
If a non zero net force acts on an object what does the object do?
-- When the net force on an object is not zero, the object undergoes accelerated motion.-- The magnitude of the acceleration is the ratio of the net force to the object's mass.-- The direction of the acceleration is the same as the direction of the net force.
Why does an object traveling in a circular path at costant speed accelerate?
An object traveling in a circular path at a constant speed undergoes acceleration because its direction of motion is constantly changing. Even though its speed remains constant, the change in direction causes an inward acceleration called centripetal acceleration. This acceleration is necessary to keep the object moving in a circular path.
What occurs when on object slows down?
It undergoes acceleration, its speed decreases, the magnitude of its velocity decreases, and it takes more time to arrive at its final destination.
What occurs when a object slows down?
It undergoes acceleration, its speed decreases, the magnitude of its velocity decreases, and it takes more time to arrive at its final destination.
What happens when centripetal acceleration occurs?
When centripetal acceleration occurs, it causes an object to move in a circular path by continuously changing the direction of its velocity. This acceleration is always directed towards the center of the circle and is necessary to balance the outward centrifugal force, keeping the object in its circular motion.
What is an example of something that undergoes acceleration while moving at a constant speed?
An object moving in a circle at a constant speed undergoes acceleration because its direction of motion is continuously changing, even though its speed stays constant. This acceleration is called centripetal acceleration and is directed towards the center of the circle.
When a body undergoes an acceleration does its speed increase or decrease?
Both. Acceleration is a change in speed.
What is the weight an object with a mass of 5.0kg?
Weight is an objects mass times the gravitational acceleration it undergoes. For a 5.0kg mass this would be 49N which equals 11.02 pounds.
What accelerates while traveling at constant velocity?
Nothing accelerates while traveling at constant velocity. Acceleration refers to a change in velocity, so if velocity is constant, there is no acceleration.
