- Q1Which of the following statements does NOT describe force?Force causes objects to start movingForce causes objects to change directionForce causes objects in motion to remain in motionForce causes objects to stop moving120s
- Q2What is the net force in a tug of war game if one team pulls 1000 N to the left and the other team pulls 1200 N to the right?2200 N left200 N left200 N right2200 N right120s
- Q3A hammer drives a nail into a piece of wood. Which of the following correctly identifies an action-reaction pair?the hammer exerts a force on the nail; the wood exerts a force on the nailthe nail exerts a force on the hammer; the hammer exerts a force on the woodthe hammer exerts a force on the nail; the hammer exerts a force on the woodthe hammer exerts a force on the nail; the nail exerts a force on the hammer120s
- Q4If a chair is sitting still on the floor, what does that tell us about the forces acting on the chair?The force of gravity is greater than the force of friction because the chair is not moving.The force of friction is greater than the force of gravity because the chair is not moving.The forces are unbalanced because the chair is not moving.The forces are balanced because the chair is not moving.120s
- Q5Which of these is an example of Newton’s first law of motion?A box will stay at rest until a force moves it.A box pushes on the floor with a force, and the floor pushes back on the box with a force.The harder I push a box the farther it will move.120s
- Q6What does Newton’s 2nd law tell us will happen to a shopping cart as more mass is added to it?It will speed up and turnIt will slow down and continue in the same directionIt will slow down and turnIt will speed up and continue in the same direction120s
- Q7If you push a 10 kg box, a 20 kg box, and a 30 kg box each with an equal amount of force, which box will move farther?The 30 kg box because it has more massThey will all move the same distance because the amount of force was the sameThe 10 kg box because it has less massThe 20 kg box because it was pushed harder120s
- Q8If you throw a golf ball and a bowling ball and they both land 5 meters away from where they were thrown, what does that tell you about the amount of force used to throw the balls?The bowling ball was thrown with more force because you have to use more force to move something with more mass.The golf ball was thrown with more force because it is easier to move something with less mass.They were thrown with the same amount of force because they went the same distance.30s
- Q9If I pull on a door with 50 N of force to open it, how much force is applied to my hand by the door as I pull on it?25 N100 N50 N0 N120s
- Q10Which of these describes a pair of action-reaction forces while you are swimming?The force of your hands and legs pushing on the water, and the force of the water pushing back on your hands and legs.The force of gravity on your body, and the force of the water pushing on you.The force of your hands and legs pushing on the water, and the force of gravity pulling you down.120s
- Q11A student pulls a 60.-newton sled with a force having a magnitude of 20. newtons. What is the magnitude of the force that the sled exerts on the student?20 newtons60 newtons40 newtons120 newtons120s
- Q12If the distance between two objects is tripled, then the gravitational force between them...is 3 times stronger.is 3 times weaker.is 9 times weaker.constant120s
- Q13An object is said to have__________________________________ if all of the forces acting on it are equal in size and opposite in direction.None of the abovebalanced forcesUnbalanced forcesLess forces120s
- Q14What does Newton’s 1st law of motion tell us about the expected motion of a kickball rolling across the floor?The ball will roll faster if it has less mass.The ball speeds up as it rolls across the floor.The ball will keep rolling until a force stops it.120s
