1) What is force ? a) A pull or a push that acts upon an object b) Energy that is used to do work c) Force that effects on an object 2) What is the force involved in the diagram shown ? a) Pushing force b) Pulling force c) Pushing and pulling force 3) What is the force applied by the paddlers to move the kayaks ? a) Pushing force b) Pulling force c) Pushing and pulling force 4) The following are the effects of force, except ... a) b) c) 5) What force involved for both of the groups in the game shown in the diagram ? a) Pushing force b) Pulling force c) Frictional force 6) What is meant by frictional force ? a) A force produced by friction b) A force generated when two surfaces are in contact c) A force applied on two objects that are in contact 7) What is the effects of the frictional force ? a) Can slow down the moving object b) Can cause the object moves faster c) Can cause the moving object change its direction 8) Based on the diagram, why is it harder to pull the box on a rougher surface ? a) Rougher surface produce less friction b) Rougher surface did not produce any friction c) Rougher surface produce greater friction 9) How to reduce friction for the situation shown in the diagram ? a) Put rollers under the box b) Put grease on the surface of the cement c) Make the box more lighter 10) Ahmad pushed 3 different metal balls with 3 different masses, 300g, 200g and 100g. Based on the masses of the ball, the 300g ball travelled the shortest distance. Why ? a) Heavier objects produced more friction b) Heavier object travelled slower c) Heavier object can cause the surface becomes rougher 11) What is meant by speed ? a) The measurement of an object travels b) The measurement of how fast or slow an object moves c) The measurement of kilometres 12) The following are the units for speed, except a) km/hour b) metre/ second c) milimetre/second 13) A bus took 2 hours to travel 200km, what is its speed ? a) 20 km/h b) 50 km/h c) 100km/h 14) What is the formula to calculate speed ? a) Time / Distance b) Time / Speed c) Distance / Time 15) What is the time taken for the car that travel 450km with the speed of 150km/h ? a) 6 hours b) 3 hours c) 1.5 hours
