[pic] The product of average force and the time it is exerted is called the impulse of force. From Newton’s second law [pic] the impulse of force can be extracted and found to be equal to the change in momentum of an object provided the mass is constant: |[pic] |Calculation | The main utility of the concept is in the study of the average impact force during collisions. For collisions‚ the mass and change in velocity are often

Universal Gravitation Apples had a significant contribution to the discovery of gravitation. The English physicist Isaac Newton (1642-1727) introduced the term "gravity" after he saw an apple falling onto the ground in his garden. "Gravity" is the force of attraction exerted by the earth on an object. The moon orbits around the earth because of gravity too. Newton later proposed that gravity was just a particular case of gravitation. Every mass in the universe attracts every other mass. This is the

Centripetal force (from Latin centrum "center" and petere "to seek"[1]) is a force that makes a body follow a curved path: its direction is always orthogonal to the velocity of the body‚ toward the fixed point of the instantaneous center of curvature of the path. Centripetal force is generally the cause of circular motion. In simple terms‚ centripetal force is defined as a force which keeps a body moving with a uniform speed along a circular path and is directed along the radius towards the centre

= 300g 9.8 3. Explain the effect of mass on Hooke’s Law. Hooke’s Law states that the restoring force of a spring is directly proportional to a small displacement. Applying a mass to the end of the spring stretches it‚ changing the length from its original equilibrium position of rest‚ to a new (lower) equilibrium position. At this position‚ the vertical restoring force of the spring balances the weight and the downward pull of gravity is balanced by the upward pull of the spring
