Answer:
1.Newton's three laws of motion may be stated as follows:
Every object in a state of uniform motion will remain in that state of motion unless an external force acts on it.
Force equals mass times acceleration [ ].
For every action there is an equal and opposite reaction.
2. Momentum is the quantity of motion of a moving body, measured as a product of its mass and velocity.
3. The momentum, p, of the object is simply the product of its mass and its velocity:
p = mv.
4. represented by the equation v = Δs/Δt
5. Energy is the strength and vitality required for sustained physical or mental activity.
