1. Force
Force is a push or a pull that can change:
the shape of an object
the speed of an object
the direction of motion
the state of rest or motion of an object
Example:
Opening a door by pushing it is an example of applying force.
2. Effects of Force
A force can:
move a stationary object
stop a moving object
change the speed of an object
change the direction of motion
change the shape of an object
3. Types of Forces
(a) Contact Forces
These forces act only when there is physical contact between two objects.
Examples:
Muscular force
Frictional force
