All of the AboveGravityMassFriction2. how many planet do we have in our solar system94273. what causes friction?Hint4. Mass is measured in what unit?KgPaN/mN5. ___ is the speed of an object and the direction of motion. VelocityGravityFrictionMass6. All of these are examples of contact forces EXCEPT:TensionBuoyant forceFrictionGravity7. A tension force is is the force that is transmitted through a string, rope, cable or wire when it is pulled tight by forces acting from opposite endsTrueFalse8. Friction acts in a direction __________ to the direction of an object's motion UnrelatedPerpendicularOppositeEqual9. A force can change Any of the aboveThe speed of an object, e.g. friction can slow down a carThe direction of an object, e.g. hitting a tennis ballThe shape of an object, e.g. sitting on a blowup mattress10. What are the two types of kinetic friction?Sliding and rollingStatic and potentialRolling and distantTension and sliding11. Gravity isA force that is only found on our planet, EarthA force that acts towards the centre of the EarthAll of the aboveA force that acts away from the Earth12. Newton's _____ law of motion explains why you may lean sideways in a car if the driver turns a corner too quickly. SecondThirdPrimaryFirst13. When we measured force in our labs we used a piece of lab equipment called a _______Spring scaleTriple beam balanceDoctor's scaleRubber band14. how many types of motion are there15. The moment of a force causes an object toStop movingMove forwardMove backwardTurn about a fixed point16. A magazine rests on top of a TV remote that is sitting on a table. Which is NOT exacting a force on the remote?The tableMagazineGravityYour hand17. How is speed calculated? Speed= distance/ timeSpeed= areaSpeed= distance × timeSpeed = displacement/ time18. Two equal and oppositely directed forces acting on an object will be in equilibrium If they are separated by a distanceOnly if they act on the same point on the objectWhen they are balanced by a third forceWhen their moments about the same point are equal19. Newton first described gravity while watching:Someone walkingA car accelerateAn apple fallingSmoke rise20. According to Newton's third law, forces always occur in ____ pairs. Equal but oppositeUnequal but complementaryUnequal but oppositeEqual but complementary21 out of 20Time is Up! Time's up
