Physics - Force And Newton's Laws Of Motion - Speed Notes

Force : Push or pull is called Force.

Example:

We push or pull to open a door.

Effects of Force

• Force can change the shape and size of an object.

• Force can move a stationary object.

• Force can change the speed of a body.

• Force can stop a moving body.

• Force can change the direction of a moving object.

Net or Resultant Force:

Resultant Force or Net Force acts on a body if two or more forces act on it at the same time. Resultant Force or Net Force on a body is defined as the net effective force due to the multiple forces acting on it simultaneously.

Based on Net force, Forces are classified into two types as:

(A) Balanced forces

(B) Unbalanced forces
