Force
- a force is a push or pull
- there are two forces acting on all objects: - gravitational force
- normal force
Contact Force
most forces require contact between objects
Non Contact Force
- some forces act at a distance
- they don't need contact
eg: gravitatonal
magnetic
electrical
Balanced Forces
- when the forces acting on an object are balanced, the object will not change speed or direction
Unbalanced Forces
- If the forces acting on an object are unbalanced, the object will accelerate
Forces and Acceleration
In science, acceleration means to 'speed up', 'slow down' or 'change direction'
Inertia
Newton's first law: Inertia
"objects will continue to do what they are doing until an unbalanced force acts on them"
Vector diagrams
vector diagrams state the net magnitude and direction of the force using arrows
