Flashcards in Newtons laws of motion and collisons Deck (14):
1

Newtons second law

Rate of change of momentum of a body is proportional to the force acting on it and takes place in the direction of the force

2

Newtons third law

When a body exerts a force on another body. The. Second body exerts an equal and opposite force on the first body

3

Linear momentum

Product of mass and velocity and has a direction

4

Net force on a body

Is equal to the rate of change of momentum

5

The special case for newtons second law

F=ma given that mass remains constant

6

Impulse of a force

Change in momentum

7

What is the area under the graph equal to on force against time

The impulse

8

Impulse

Change in momentum mu-mv

9

Principle of conservation of momentum

The total momentum of a closed system is conserved

10

Perfectly elastic collision

All kinetic energy is conserved

11

Inelastic collision

Kinetic energy is not conserved

12

Newtons first law

A body will remain at rest or continue at a constant velocity unless acted upon by a force

13

momentum is conserved but in what does a change occur

The momentum of a system is always conserved in the interaction between bodies but some change in kinetic energy usually occurs

14

Force equals

∆p/∆t
