A ball is rolled across a flat surface covered by carpet. Then, with same equal force, the ball is rolled on a flat, smooth surface. Which best explains why the ball rolls slower on the surface covered by carpet than on the smooth surface?

• There is less gravity between the ball and the carpet.

• There is less friction between the ball and the carpet.

• There is more gravity between the ball and the carpet.

• There is more friction between the ball and the carpet.

Which demonstrates a force being used to increase the speed of an object?

• wind pushing the sails of a sailboat

• a farmer pulling on the reins of a horse

• a driver pressing on the brakes in a truck

• a parachute opening during a person’s jump

A girl walked for 30 minutes. She noticed that she traveled farther in the first 15 minutes of her walk than in the second 15 minutes. What can she conclude about her walk?

• She walked over many hills.

• Her average speed was faster during the first half of her walk.

• She walked in two different directions.

• She was walking at a constant speed.

Which tool can best be used to measure the direction in which an object is moving?

• a ruler

• a watch

• a compass

• a barometer
