What is inertia?
|
It is a tendency to resist any change in motion
|
|
|
What is Newton's first law of motion?
|
Any object that is moving or is at rest will remain so until an external force acts upon it
|
|
|
What is Newton's second law of motion?
|
An object will accelerate in the direction of an unbalanced force acting upon it. The size of this acceleration depends upon the mass of the object and the size of the force acting
|
|
|
What is Newton's third law of motion?
|
For every action force there is an equal and opposite reaction force
|
|

What is velocity?
|
Velocity is distance travelled in a direction measured in units of time
