Forces Investigation Quiz

A student is conducting an investigation on forces. The student rolls a log down a hill. Which surface on the slope of the hill makes the log roll the fastest?

• Smooth grass, because it produces the least friction

• Loose sand, because it produces the least friction

• Rocky ground, because it produces the most friction

• Bushes, because they produce the most friction

A student is investigating how much force is needed to slide a box across the floor using a contact force. Which statement describes a contact force?

• A force between objects that attract or repel each other

• A force that slows down an object that is moving

• A force that is applied when objects touch

• A force that speeds up an object that is moving

Look at the picture. Kiesha wants to build a ramp for her dog to safely walk up and down. She plans an investigation to test different ramp materials. Choose the words that complete the sentences. The force between her dog and the ramp is a __________ force. The safest material for the ramp will have the __________ friction between the dog’s paws and the ramp.

• contact; most

• contact; least

• noncontact; most

• noncontact; least

1. Look at the drawing. A student wants to investigate magnets. Two magnets are placed so the shaded areas are next to each other. The shaded ends are the same poles.

Which best describes what happens if the two magnets are pushed toward
each other?

• 1. The shaded ends of the magnets attract and come together.

• 1. The shaded ends of the magnets repel and move apart.

• 1. The shaded ends of the magnets repel and come together.

• 1. The shaded ends of the magnets attract and move apart.

A student is experimenting with different materials to see how they affect the speed of a toy car rolling down a ramp. Which material will make the car roll the slowest?

• Carpet, because it produces the most friction

• Wood, because it produces moderate friction

• Metal, because it produces the least friction

• Plastic, because it produces moderate friction
