Force is defined as

(a)

Contact force

is measured in Joules

occurs between objects in physical contact

such as gravity

occurs between objects not in physical contact

Distance force

Measured in Newtons

occurs between objects in physical contact

Such as friction

Occurs between objects not in physical contact

Power

is measured in Newtons

is the rate of work

is the product of force and velocity

is the product of force and displacement

Newtons first law states that

a moving object can randomly change speed

acceleration is dependent on the force

for every action there is a reaction

A stationary object will only move if a force acts on it

10.

Newtons second law states that

Acceleration is independent on the force applied

Acceleration is directly proportional to mass

Acceleration is inversely proportional to mass

Acceleration is dependent on the force applied
