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.

From a kinematic perspective, whenever an object's velocity changes at a constant rate it is in uniform acceleration.From a dynamic perspective, whenever the net force on an object is constant the object will undergo uniform acceleration.


The object will undergo rotational acceleration: it will either rotate faster or slower than previously.



When a force acts upon an object, and that force is great enough to overcome initial friction, the object will undergo an acceleration until the force is removed or is balanced by another force.




If the mass of an object doubles while the force remains constant, the acceleration of that object will be halved. force=mass*acceleration; therefore acceleration=force/mass


The acceleration of an object is related to velocity since acceleration is the rate of change of velocity.


Acceleration of an object is directly proportional to the force on the object. When force increases, acceleration increases. I'll bet you knew that.


This object is changing its position, its velocity, and its acceleration.This object is changing its position, its velocity, and its acceleration.This object is changing its position, its velocity, and its acceleration.This object is changing its position, its velocity, and its acceleration.


Such and object is said to be in equilibrium. No acceleration and no force.


An object with constant velocity has no acceleration.


Force is any influence that allows an object to undergo change. Force is also Mass x Acceleration, and acceleration is a change in velocity. Therefore, the more force you have, the more positive acceleration you have, and therefore the higher the speed.


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.


The larger the force acting upon an object, the greater the acceleration of the object.


If you increase the force on an object acceleration increases . As F = m*a, where F = Force , m = mass of the object & a = acceleration


Acceleration is a net force that is inversely dependent on mass, therefore if an object mass increases ,acceleration decreases


Positive acceleration is an increased speed, i.e. acceleration acts in the same direction that the object is moving.


As an object approaches the Earth's surface, what will its acceleration be?


An object will have constant acceleration if the net force on it is constant in magnitude.


Object shows acceleration when the force applied on it is increased.


Velocity. A change in VELOCITY will always indicate the acceleration of an object.


Force and acceleration are NOT the same. If you apply a net force to an object, it causes the object to accelerate. The amount of acceleration depends on the force and the mass of the object. Force = mass x acceleration.


If acceleration means to increase in speed or pace, then a stationary object is static, without movement, without acceleration. But, if an object is moving at a constant rate, then I suggest acceleration is not present, unless, or until the objects speed increases. Yes, an object with no acceleration may be stationary.
