 # FORCE AND PRESSURE FORCE Force Force is a

• Slides: 16 FORCE AND PRESSURE. . . FORCE Force • Force is a push or pull developed due to interaction between objects. • Force has both magnitude and direction. • The strenghth of the force is its magnitude. • Unit of force is Newton.   Net force • When a number of individual forces are applied on a body, the resultant force is known as net force. • If forces F 1 and F 2 are applied on a body in same direction, the net force will be F = F 1+ F 2. • If forces F 1 and F 2 are applied on a body in an opposite direction, the net force will be difference between these two forces. ( suppose F 2 > F 1, the net force will be F 2 -F 1 and the body moves towards the direction of F 2). • If forces F 1 and F 2 are applied on a body in an opposite direction and F 1 = F 2, the net force F= 0 Forces in same direction F=F 1 + F 2 Forces in opposite direction(F 2>F 1) F=F 2 - F 1 Forces in opposite directions( F 1 = F 2) F= 0 Effect of force • Force can change the state of motion of an object. • Force can change the shape of an object. • Force can change the direction of an object. • Force can alter the speed of moving object. • Force can bring about some of these changes together. Changing of state of rest Changing the state of motion Changing the direction Changing the shape Changing the speed Mutiple Effects Thank you. . .
