Diagram shows a lump of plasticine of mass 0.06 kg move towards a wall with velocity 9 ms-1 and stick on the wall. Meanwhile a tennis ball of the same mass with plasticine move towards the wall with the same velocity and rebound with the velocity 6 ms-1.
Rajah menunjukkan seketul plastisin berjisim 0.06 kg bergerak menuju dinding dengan halaju 9 ms-1 dan melekat pada dinding tersebut. Manakala sebiji bola tenis dengan jisim yang sama dengan plastisin bergerak menuju dinding dengan halaju yang sama dan melantun dengan halaju 6 ms-1.
Compare the impulse acting on the plasticine and the tennis ball.
Bandingkan impuls yang bertindak ke atas plastisin dan bola tenis.
Impulse plasticine > impulse tennis ball
Impuls plastisin > impuls bola tenis
Impulse plasticine = impulse tennis ball
Impuls plastisin = impuls bola tenis
Impulse plasticine < impulse tennis ball
Impuls plastisin < impuls bola tenis
