Forces Review

Maya and Mason were observing a soccer ball at rest on the field. They noticed that the ball remained at rest until Abigail kicked it, and then it continued moving at a constant velocity until it hit a wall. This observation is also known as:

• Law of Motion

• Law of Gravity

• Law of Friction

• Law of Inertia

Abigail, Avery, and Charlotte were helping their parents clean the garage. Which of the following scenarios is an example of static friction?

• Abigail tries to push a heavy box, but it doesn't move

• Avery pushes a heavy box and it moves easily

• Charlotte rolls a ball on the flat garage floor

• Abigail slips while walking on a wet floor

Michael is sliding a box over the floor and notices a force that opposes the motion of the box. This force is called:

• gravity

• friction

• momentum

• inertia

Luna and Noah are studying physics. They learned that the force of gravity between two objects depends on their masses and the:

• distance between them

• color of the objects

• temperature of the objects

• shape of the objects

Jackson, Emma, and Elijah are playing with a toy car. They notice that the car stops after a while when they stop pushing it. Which of the following forces is responsible for this?

• Friction

• Gravity

• Magnetism

• Electricity

Priya, Evelyn, and Aiden are conducting a science experiment. They are trying to calculate the acceleration due to gravity on Earth. They found that it is approximately:

• 9.81 m/s²

• 12.34 m/s²

• 1.23 m/s²

• 5.67 m/s²

Aria, Kai, and Avery are conducting an experiment where they drop a ball from a tall building. According to physics, what would be the acceleration of the ball in free fall?

• 0 m/s^2

• 5 m/s^2

• 9.8 m/s^2

• 20 m/s^2

Avery, Lily, and Liam are playing a game of pool. Avery hits the cue ball, which then hits another ball. The cue ball stops, but the other ball moves. Which of Newton's laws of motion explains this scenario, stating that for every action, there is an equal and opposite reaction?

• Newton's first law of motion

• Newton's second law of motion

• Newton's law of universal gravitation

• Newton's third law of motion

Emma, Ethan, and Sophia are playing a game of tug-of-war. They noticed that when they pull with a certain force, the rope doesn't move. This force they are applying to keep the rope at a constant position despite the opposing force is called:

• balancing force

• accelerating force

• net force

• opposing force

Ava, Scarlett, and Kai are playing tug of war. If the game is in equilibrium, the sum of all the forces they are exerting is:

• Non-zero

• Zero

• Negative

• Positive
