What is a force?
A push or pull upon an object
100
What is acceleration?
How velocity changes over time
100
What is unbalanced force mean?
A force that cause a change in the in the object

Moving mass has kinetic energy.
200
What is the 1st,2nd,and 3rd law of motion
What is the 1st,2nd,and 3rd law of motion1st=An object in motion will stay in motion unless and unbalanced force acts upon it 2nd=the strength of a force equal to the amount of mass involved multiplied by any acceleration applied to it. 3rd=For every action there is an equal and opposite reaction. Also known as action and reaction.

A spring scale
200
What is the formula acceleration?
a=f/m(acceleration=force/mass)

What is balanced force?
forces that are equal in size but opposite in direction are called balanced force
