[ Junior school science (physics) ] ____ is NOT a force. FrictionMassGravityAll of the Above2. [ Junior school science (physics) ]What are the two types of kinetic friction?Rolling and distantStatic and potentialTension and slidingSliding and rolling3. [ Junior school science (physics) ]The moment of a force causes an object toStop movingMove backwardMove forwardTurn about a fixed point4. [ Junior school science (physics) ] How is speed calculated? Speed= areaSpeed= distance × timeSpeed= distance/ timeSpeed = displacement/ time5. [ Junior school science (physics) ]When the buoyant force pushing up on an object is equal to the force of gravity pushing down on the object, the object will sink.FalseTrue6. [ Junior school science (physics) ]how many types of motion are there7. [ Junior school science (physics) ]All of these are examples of contact forces EXCEPT:TensionGravityBuoyant forceFriction8. [ Junior school science (physics) ] A nut can be loosen more easily with A heavy spanner because a larger force can be produced.long spanner because a large turning effect can be produced.A short spanner because a large turning effect can be produced.A short spanner because a larger force can be produced.9. [ Junior school science (physics) ] What are the units of force? NewtonJoulesCentimetreKilogram10. [ Junior school science (physics) ]If there was no gravity, would we weigh anything?NoYes11. [ Junior school science (physics) ]The size of the gravitational force depends on the ___________ of the objects and the ____________________ the objects.Distance, pull ofDistance, size ofMasses, distance betweenWeight, distance between12. [ Junior school science (physics) ] Scientists express force by using a unit called the: Newton (N)Kg/mJoule (J)Pound (lb)13. [ Junior school science (physics) ]The force that always acts opposite to the direction of the motion of an object is called:FrictionInertiaNone of the aboveGravity14. [ Junior school science (physics) ]It would probably be easiest to ride a bicycle across:GravelSidewalkvSandGrass15. [ Junior school science (physics) ]The amount of force needed to lift an object depends on the object'smasssizeenergygravity16. [ Junior school science (physics) ] ___ is the speed of an object and the direction of motion. FrictionVelocityMassGravity17. [ Junior school science (physics) ]A magazine rests on top of a TV remote that is sitting on a table. Which is NOT exacting a force on the remote?MagazineYour handGravityThe table18. [ Junior school science (physics) ] A (n) ______________ can cause an objects motion to change Unbalanced forceInertiaBalanced forceMass19. [ Junior school science (physics) ] Friction acts in a direction __________ to the direction of an object's motion UnrelatedPerpendicularEqualOpposite20. [ Junior school science (physics) ] A force can change The shape of an object, e.g. sitting on a blowup mattressThe speed of an object, e.g. friction can slow down a carAny of the aboveThe direction of an object, e.g. hitting a tennis ball21 out of 20Time is Up!
