Issac Newton defined 3 laws of
motions that relate to how an object behaves on earth;
Inertia – An Object at rest will remain at rest unless
acted on by an unbalanced force. An object in motion continues in motion with
the same speed and in the same direction unless acted upon by an unbalanced
force.
Acceleration – Acceleration is produced when a force acts on a mass.
The greater the mass (of the object being accelerated) the greater the amount
of force needed (to accelerate the object)
Reaction – for every action there is an equal and opposite
reaction.
