The definition of acceleration is ratio of change to velocity of change in time. Therefore, acceleration is best expressed with distance/ square of time, so ft/s2 and m/s2.

An object will have constant acceleration if?
well, something has to be pushed by a constantly growing force. Constant acceleration would occur for example if you drop something in a vacuum. Dropping something in normal circumstances is a nearly constant acceleration too.
Does acceleration occur if the force is outside a system?
For acceleration, there must be a net force on an object. The force can come from anywhere. Internal forces - between parts of a system - will not cause an acceleration of the system as a whole, i.e., of its center of mass; such forces come in pairs, and - considering the system as a whole - they cancel one another.
Find mass given force and acceleration?
Force = mass x acceleration. Mass must be in kilograms and acceleration must be in meters per second squared.
What condition are necessary for acceleration to occur?
you need both a mass (m) and a force (F) applied to it to get acceleration (a); F = ma
Should acceleration be constant?
Acceleration must be constant to use kinematic equations. Acceleration need not be constant if working with energy.
Acceleration occur when velocity changes?
Only the acceleration brings a change in velocity.
If there is a constant velocity of 30 ms. What is its acceleration?
Unless the object is changing its direction, it is not accelerating. Constant velocity implies that speed and direction are constant, and for acceleration to occur, either speed, direction, or both values must be changing.

When does acceleraion occur?
Acceleration occurs when there is unbalanced force applied to an object.
Must mitosis occur in budding?
Mitosis must occur in budding.
Is it true or false that acceleration can only occur when the speed of an object changes?
No. Acceleration is change of velocity. It occurs when an object changes speed and/or direction.
How does acceleration occur?
acceleration work by speed when something is going fast and when it and go over or faster with something.
If an object falls with constant acceleration the velocity of the object must?
Changing at a constant rate equal to acceleration.
