1

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

8

A force of 160 N on a bike produces acceleration of 2m/s^2, what the total inertial mass?

160/2 = 8
