Forces(Physical world)
A force is anything that causes an object to change its shape,speed or direction of movement
Learning intentions:
1: define the term force 2:calculate force using the formula
3: describe contact and non contact forces
4: explain newton's 1st,2nd,3rd law of forces
5:describe the difference between mass and weight
6:define the term friction
7:explain balanced and unbalanced forces
8: illustrate and describe hooke's law
Mass: This is the amount of matter in an object
Weight:This is the downwards force of an object due to gravity
A contact force is a force that touches an object in order for it to change speed, shape or direction of movement.
A non-contact force is a force that does not touch an object in order to change its shape, speed or direction of movement.

Newtons first law: An object that isn't moving will not move and an object that is moving will stay moving. Newton's third law: For every action there is an equal and opposite reaction.
Newtons second law The acceleration of an object is directly proportional to the strength of the force applied
Force (F)= mass(m) x acceleration
The greater the force the greater the acceleration; these are directly proportional

Gravitational field strength- the force per unit mass, measure in newtons per kilogram (N/kg)
The more mass an object has, the greater this force will be
