## What does Newton’s second law describe?

### The factors that affect the acceleration of an object

2

## What are the factors that affect the acceleration of an object in Newton’s second law

###
The acceleration in the direction of a resultant force depends on:

The size of the force and the mass of the object

3

## What is the formula linking force, mass and acceleration?

###
Force = mass x acceleration

N Kg m/s^2

4

##
A motorcycle has a mass of 200kg. What force is needed to give it an acceleration of 7m/s squared?

### 200 x 7 = 1400 N

5

## What is the inertial mass?

### The force on the object divided by the acceleration that the force produces

6

## The more massive an object is...

### ...the more force is needed to change it’s velocity

7

## What does calculating an object’s inertial mass from values of force and acceleration give?

### The same mass value as that by measuring the force of gravity on it
