Newton's laws and momentum GapFill

In the 17th century, Isaac Newton formalised three laws of motion which describe how bodies react to forces.
Newton's first law of motion states that an object without a resultant exerted force will  undergo circular motionremain at restundergo simple harmonic motionremain at rest or at constant velocity.
Newton's second law of motion states that the resultant force exerted on a body is  proportional toperpendicular togreater thanless than that body's acceleration. This can also be expressed as  F = m - aF = maF = √(ma)F = m + a.
Newton's third law of motion states that any force on a body will result in  an equal, opposite and similaran equal, opposite and different type ofa different type ofan increasing force being exerted by the body.

Momentum is an important quantity when discussing motion. The total momentum of a closed system is always conserved, no matter the collisions and interactions that occur within that system. Momentum is given by the equation  p = m ÷ vp = m - vp = Δ(mv)p = mv.
The  change in potential energy ofchange of momentum ofrate of change of momentum offorce exerted on a body during a collision is called the impulse of the collision.
Force exerted on a body is equal to the  change in potential energy oftotal momentum ofrate of change of momentum ofdistance moved by a body.
Collisions in which kinetic energy is conserved are called  inelasticelasticfastslow collisions, and when kinetic energy is not conserved they are called  elasticwastednon-kineticinelastic collisions.
