KSSM PHYSICS FORM 4 58 CONTENT STANDARD LEARNING STANDARD NOTES Note: Discussion is restricted to collision and explosion in one dimension. 2.6 Force Pupils are able to: 2.6.1 Define force as the rate of change of momentum. Suggested activity: Carry out activities to generate ideas on the relationship between: force and acceleration mass and acceleration Introduce Newton’s second law of motion. Note: Newton’s second l aw of motion states that the rate of change of momentum is directly proportional to the force and acts in the direction of the force: 1 k where kma; F 2.6.2 Solve problems involving F= ma t mu mv F ma F ma F

KSSM PHYSICS FORM 4 59 CONTENT STANDARD LEARNING STANDARD NOTES 2.7 Impulse and Impulsive Force Pupils are able to: 2.7.1 Communicate to explain impulse and impulsive force. Suggested activity: Carry out activities and discuss: the effect of increasing or decreasing time of impact on the magnitude of impulsive force. situations and applications involving impulse in daily life. situations and applications involving impulsive force in the safety features in vehicles. Introducing Newt on’s third law of motion. Note: Newton’s third law of motion states that for every action, there is an equal but opposite reaction. Impulse is the change of momentum: Impulse, Ft = mv mu Impulsive force is the rate of change of momentum in collisions that happen in a short period of time.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
