📚 Part 1: Newton's Laws and Forces Fill-in-the-Blank

1. Complete the following statements about Newton's Laws:

Newton's First Law: An object at rest will remain at rest, and an object in motion will continue moving at _____________ velocity, unless acted upon by an _____________ force.

Newton's Second Law: When a net force acts on an object, it causes _____________. This relationship is expressed by the formula: _____ = _____ × _____

2. When a toy car rolls down a ramp, gravity can be split into two components:

a) One component acts _____________ to the ramp surface (balanced by the normal force)

b) One component acts _____________ to the ramp, pulling the car down the slope

3. Fill in the blanks about forces on a ramp:

As the ramp angle increases, the component of gravity acting parallel to the ramp _____________. This means the car will accelerate _____________ down a steeper ramp.

4. What is friction?

Friction is a force that _____________ motion. On a ramp, friction acts _____________ the ramp (opposite to the direction of motion).

5. The net force causing acceleration down a ramp is:

Net force = _____________ component of gravity - _____________

✏️ Part 2: Short Answer Questions

6. Explain why a toy car accelerates faster down a steeper ramp. Use the concept of gravity components in your answer.

7. A toy car is sitting on a flat table. Identify all the forces acting on the car and explain why it doesn't accelerate.

8. Calculate the weight of a toy car with a mass of 0.25 kg on Earth. (Use g = 10 N/kg)

📊 Part 1: Identifying Variables

1. In an experiment where a toy car rolls down a ramp, identify the independent and dependent variables.

2. Describe how changing the angle of the ramp affects the speed of the toy car. What variable is being manipulated?

3. If you were to add weights to the toy car, how would this affect its acceleration down the ramp? Identify the variables involved.

4. Compare the motion of two toy cars rolling down ramps of different angles. What factors would you consider when analyzing their motion?

5. Discuss how friction plays a role in the motion of the toy car on the ramp. How does it affect the dependent variable?
