Sample questions

1. When you push a toy car across the floor, which force are you primarily applying?

   1. Friction
   2. Gravity
   3. Push
   4. Pull
   Show answer

   Answer: C. Push

   A push is a force that moves something away from the source of the force. When pushing a toy car, you are applying a force away from yourself to move the car.

2. Which of the following pairs of surfaces would likely have the highest friction when rubbed together?

   1. Polished glass and smooth metal
   2. Wet ice and a ski
   3. Sandpaper and wood
   4. Ball bearings and a smooth track
   Show answer

   Answer: C. Sandpaper and wood

   Friction depends on the nature of the surfaces in contact. Sandpaper is designed to be rough, creating high friction against wood, which is also relatively rough. The other options involve smoother surfaces or reduced friction mechanisms.

3. Which of the following is a force that pulls objects towards the center of the Earth?

   1. Friction
   2. Push
   3. Gravity
   4. Applied Force
   Show answer

   Answer: C. Gravity

   Gravity is the force of attraction between any two objects with mass. Earth's gravity pulls all objects towards its center.

4. Which of these actions demonstrates a force causing a change in shape without causing significant movement?

   1. A car accelerating
   2. A rubber ball bouncing
   3. A chef mashing potatoes
   4. A kite flying in the wind
   Show answer

   Answer: C. A chef mashing potatoes

   Mashing potatoes involves applying a force to deform them, changing their shape, rather than making them move significantly across a distance.

5. You are trying to slide a box across a floor. If you increase the normal force (by adding weight to the box), the force of static friction will:

   1. Decrease
   2. Stay the same
   3. Increase
   4. Become kinetic friction
   Show answer

   Answer: C. Increase

   The maximum static friction is directly proportional to the normal force pressing the surfaces together. Increasing the weight increases the normal force and thus increases static friction.
