Physics r13

• The push or pull on an object is called as force
• Force cant be seen but its effects can be seen.
• Forces are measured in Newtons (N)
• Forces usually act in pairs
• Forces always act in a certain direction
• Newton meter is used to measured the forces
• Examples of non-contact forces are gravitational, electrostatic and magnetic.
• Forces can make objects do the things like start moving or speed up, change shape, turn, change direction, slow down or stop moving
• Balanced Forces produce no change in movement
