Upper Elementary Science - II
4.12 Force

Force is that which changes or tends to change the state of rest or motion of a body. There are usually several forces acting on an object.

The forces might:

  • change the speed of a moving object
  • change the direction of a moving object
  • change the shape of an object
Here are some forces that act in nature:

Air resistance: When an object moves through the air, air resistance acts in the opposite direction to the motion. Air resistance depends on the shape of the object and its speed.

Contact force: Contact force happens when two objects are pushed together.

Friction: The force which resists movement between two surfaces which are in contact.

Gravity: The force which pulls objects towards the Earth. We call the pull of gravity on an object its weight.
