1. Newton’s first law states that no [acceleration / inertia] can happen without a force.

• ACCELERATION

• INERTIA

Multiple Choice

For each of the following questions about Newton’s laws of motion, circle the correct answer to complete the sentence.​

2. When a raindrop strikes a brick wall, the force the raindrop applies to the brick wall is [greater than / equal to / less than] the force the brick wall applies to the raindrop.

• GREATER THAN

• EQUAL TO

• LESS THAN

Multiple Choice

For each of the following questions about Newton’s laws of motion, circle the correct answer to complete the sentence.​

3. Two identical boxes are placed on the ground next to each other. One is empty, and one is filled with sand. It would take [more force / the same amount of force / less force] to pull the empty box than the box with sand.

• MORE FORCE

• THE SAME AMOUNT OF FORCE

• LESS FORCE

Multiple Choice

For each of the following questions about Newton’s laws of motion, circle the correct answer to complete the sentence.​

4. When a hammer strikes a nail, the direction of the force the hammer applies to the nail is [the same as / opposite from] the direction of the force the nail applies to the hammer.

• THE SAME AS

• OPPOSITE FROM

Multiple Choice

• MASS

• FRICTION

​Look at the illustrations of two shopping carts. Circle the cart that would be harder to move. Explain why this is so.​

Multiple Choice

Look at the illustrations of two shopping carts. Circle the cart that would be harder to move. Explain why this is so.​

• The cart would be harder to move because the wheels are smaller, making it harder to push.

• The cart would be harder to move because it is on a smooth surface, which increases friction.

• The cart would be harder to move because it is a different color, which makes it heavier.

• Second shopping cart has grater mass.

Multiple Choice

Explain how a person taking a nap on a grassy meadow is an example of inertia.

• 1. The grass makes them sleepier.

• 1. Their body absorbs energy from the sun.

• • The person stays at rest until an external force acts on them.

• 1. Nature keeps them calm.

​Make three drawings to illustrate Newton’s three laws of motion. Label your drawings with the name of the law and other important words.​

PROJECT III: FORCE&MOVEMENT

​Instructions for Designing a Model in Tinkercad

1. Log in to Tinkercad and create a new design.

2. Choose to illustrate a push-pull mechanism or ANY of Newton's three laws (inertia, F=ma, or action-reaction).

3. Use basic shapes to create the model's base.

4. Add moving parts like sliders or levers.

5. Use arrows to indicate forces and label them.

6. Ensure the model accurately represents the chosen concept.

7. Save and export the design.

8. Write a brief explanation of your model.

9. Review and share your model.
