Newton's First Law of Motion
Newton's first law of motion states that if all the forces acting on an object are in 'equilibrium', the object in question will remain at the speed/ velocity it is heading;This includes stationary. So basically, if all the forces acting on a moving car are of equally balanced values then the car will remain at that speed until a resultant force is applied.
Newton's Second Law of Motion
Newton's second law of motion states that if there is a resultant force, there will be a change in velocity, i.e. acceleration. In addition, this law highlights that the acceleration is proportional to the resultant force.
Resultant force (F) = Mass (m) x Acceleration (a)
F = ma
Newton's Third Law of Motion
Newton's third law of motion relates to the idea that if body A exerts a force on body B, then body B will exert a force of body A of the same magnitude but an opposite direction.
For example, the Earth exerts a gravitational force of 10N on a rock, so the rock exerts an upwards gravitational force of 10N on the Earth.
