The chart below shows four identical wagons loaded with different amounts of bricks.

If the same amount of effort is applied to all four identical wagons, why would Wagon W move farthest?

• It has the least amount of mass, affecting its motion.

• It has the least amount of speed, affecting its motion.

• It has the greatest amount of gravity, affecting its motion.

• It has the greatest amount of friction, affecting its motion.

How fast was a train moving if it traveled 100 meters in 10 seconds?

(speed = distance ÷ time)

• 1 meter per second

• 10 meters per second

• 90 meters per second

• 100 meters per second

A 30 gram ball rolls along a flat surface at a constant speed in the same direction over 4 meters in 20 seconds. Which is the speed of the ball?

(speed = distance ÷ time)

• 0.2 meters per second

• 0.5 meters per second

• 20 meters per second

• 80 meters per second

The graph below shows the speed of runners during a race.

How can the movement of the runners be accurately compared

(speed = distance ÷ time)?

• The red runner had a faster start than the green runner.

• The red runner ran at constant speed for a longer duration than the green runner.

• The red runner stopped running for a longer duration of time than the green runner.

• The red runner had more changes in speed than the green runner in the first 45 seconds.

Walker pulled an empty cart to the library. When she leaves the library, the cart is full of books. How does the force of friction on the cart change?

• The force of friction increases because there is more mass.

• The force of friction decreases because there is more air pressure.

• The force of friction increases because the force of gravity decreases.

• The force of friction stays the same because Maria is still pulling the cart with the same force.

A plane carrying bags has a mass of 50,000 kg. After delivering the bags, it has a mass of 30,000 kg. Which would best describe how the plane’s motion would be affected on the way back?

• The plane would travel at a faster speed.

• The plane would travel at a slower speed.

• The plane would travel at the same speed.

Water evaporates quickly in the hot part of the day. Water that evaporates goes into the air. It does not stay in the soil.

Penny needs to water her vegetable garden. She wants most of the water to stay in the soil. That way, her plants can use the water. When should she water her garden?

• 6 a.m.

• 10 a.m.

• 2 p.m

• 10 p.m.
