The SI unit for measuring force is newtons (N)

Effects of force

• ​It can increase the speed of a moving object or make a stationary object start moving.
• Slow down or stop a moving object.

Force is that which changes a body’s state of motion or shape. Some forces are small and others are large.
Force is represented by a line with an arrow showing the direction it acts. i.e.
