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
