During a physics class experiment, Yuilbert, Maddy, Jorden, Keyli, and Brayden applied an equal force to push different boxes. Each box had a different weight: 30 kg, 15 kg, 150 kg, and 40 kg. If they pushed all of the boxes on the same surface for the same amount of time, which box will MOST LIKELY move the greatest distance?

• F. 30 kg

• G. 15 kg

• H. 150 kg

• J. 40 kg

While Jorden and Camila were playing soccer, they noticed that the ball slows down after a while even if no one touches it. This is due to a type of force called ______________________.

• force

• gravity

• energy

• friction

Maddy is playing with her toy car. She notices that when she applies a ________________ to the car, it moves. What is this push or pull called?

• force

• gravity

• energy

• friction

(2) During the school picnic, Mrs. Giet's class decided to play tug of war. Team A consisted of Jorden, Keyli, Camila and 8 other girls, while Team B had Brayden, Yuilbert and 4 other boys. As soon as the game began, Team A was able to pull the rope to their side. Why?

• There was an equal amount of force pulling on each side making it unbalanced.

• There was an equal amount of force pushing on each side making it unbalanced.

• There was more force on Team A's side making it unbalanced.

• There was less force on Team A's side making it unbalanced.

(7) Which scenario is showing gravity as the main force moving an object?

Keyli was observing her surroundings and noticed a few events. Which of these events, observed by Keyli, is showing gravity as the main force moving an object?

• Brayden's pencil fell to the ground when he dropped it.

• Camila saw a plane taking off.

• Jorden noticed a feather floating in the wind.

• Yuilbert threw a ball up in the air.

(1) Yuilbert is skydiving and uses a parachute to slow his descent to the ground. What statement explains this science fact?

• Yuilbert has less gravity because the parachute makes him smaller.

• Yuilbert has more gravity because the parachute catches wind and makes him heavier.

• The parachute causes air resistance and decreases the force of gravity on Yuilbert.

• The parachute causes air resistance and increases the force of gravity on Yuilbert.
