Forces and Pressure
10.1 What is a Force?O A force is a push or pull.O Forces can be classified into contact
or non-contact forces.O Other examples of forces:
O SqueezingO TwistingO StretchingO Folding
Effects of ForcesO A force can
O change the shape of an object.O change the size of an object.O make an stationary object move.O stop a moving object.O change the speed of an object by making
it to move faster or slower.O change the direction of a moving object.
