A
it is a measure of the tendency of an object to keep moving

Q
How do we calculate momentum
A
momentum (kg m/s) =mass (Kg)x velocity (m/s)

walking 1.5 m/s, running 3 m/s, cycling 6 m/s.
5
Q
What is inertial mass
A
Inertial mass is a measure of how difficult it is to change the velocity of an object.
6
Q
Newtons first law
A
an object remains in the same state of motion unless a
resultant force acts on it.
7
Q

A
F = MA
8
