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.

What happens to an object when it undergoes acceleration is it the speed or velocity that increases?
It is the velocity that increases.
When forces are balanced compare the acceleration of an object at rest and an object in motion?
An object at rest has zero acceleration. If the set of forces acting on a moving object is balanced, then the moving object also has zero acceleration.
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.
What happens to the acceleration of the object when force applied reduced to one third?
F = M A Acceleration is directly proportional to force. When force applied to an object is reduced to one third, the object's acceleration is reduced to one third.
2nd law of newton?
The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased. To put it as it is often put: Force equals mass times acceleration (F = ma): the net force on an object is equal to the mass of the object multiplied by its acceleration.
When an object undergoes an acceleration?
when it is acted on by a force
What happens to an object when it undergoes acceleration is it the speed or velocity that increases?
It is the velocity that increases.
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.
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?
If, as you say, its acceleration is "constant", then the average is exactly equal to that constant.
What accelerates while traveling at constant velocity?
An object in uniform circular motion undergoes constant acceleration but moves at constant "speed".Constant "velocity" means no acceleration.
How do unbalanced forces affect an objects velocity?
When the forces on an object are unbalanced, the object undergoes acceleration. Its direction is the direction of the net effective force, and its magnitude is the magnitude of the net effective force divided by the object's mass.
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.
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 is the mass of a book that weighs 70N?
Weight is the mass of an object times the gravitational acceleration it undergoes. The gravitational acceleration of Earth is approximately 9.8 m/s^2. So in this case 70/9.8 = 7.14 kg
If a car turns right can acceleration be zero?
No, any turning object undergoes acceleration because the direction is always changing. The acceleration vector points into the circle of rotation, and the velocity vector is a tangent line to the circle at any given point. The equation is Centripetal Acceleration=v^2/r
