Physical Science (Part 1)

A ball is kicked across a sidewalk and onto a road covered in small rocks.

Which best describes the effect the rocky road will have on the ball?

• The rocky road will decrease the speed of the ball because of its mass.

• The rocky road will increase the speed of the ball because of its mass.

• The rocky road will increase the speed of the ball because of friction.

• The rocky road will decrease the speed of the ball because of friction.

• It is slowing down.

• It is moving backwards.

• It is moving at a constant speed.

Which is the best example of a physical change?

A girl washes her favorite sweater. She hangs it outside on a clothesline in the

sun. Two hours later, the sweater is dry. What happened to the water in the

sweater?

• The water lost energy to its surroundings.

• The water condensed and flowed out of the sweater.

• The water absorbed heat energy and evaporated.

• The water transpired and evaporated.

A boy puts several kilograms of rocks in an empty wagon. How will the motion of

the wagon be different after it is filled with rocks?

• It will be easier to speed up and slow down.

• It will be more difficult to speed up and slow down.

• It will be easier to speed up, but more difficult to slow down.

• It will be more difficult to speed up, but easier to slow down.

A skydiver jumps from an airplane with a parachute. Which best explains how

forces affect the skydiver’s fall?

• Gravity pulls her down and friction slows her fall.

• Friction pulls her down and gravity slows her fall.

• Friction pulls her down and gravity makes her lighter, so she falls slower.

• Gravity pulls her down and friction makes her heavier, so she falls faster.

Which wagon would require the greatest force to stop its motion at the bottom of

the hill?

• the wagon with 5 kilograms of sand

• the wagon with 10 kilograms of sand

• the wagon with 15 kilograms of sand

• the wagon with 20 kilograms of sand
