🚗 Part 1: Understanding Speed and Motion

1. What is the formula for calculating speed?

Speed = Distance × Time

Speed = Distance ÷ Time

Speed = Time ÷ Distance

Speed = Distance + Time

2. If a toy car travels 3 metres in 2 seconds, what is its speed?

1.5 metres per second

6 metres per second

5 metres per second

3 metres per second

3. Which factors could affect the speed of an object rolling down a ramp? (Select all that apply)

Height of the ramp

Type of surface at the bottom

Weight of the object

Shape of the object

The colour of the object

4. What type of energy does an object have at the top of a ramp before it starts moving?

Kinetic energy

Potential energy

Heat energy

Sound energy

📊 Part 2: Recording Your Investigation

5. Record your experimental data in the table below:

Distance travelled: _________ metres

Ramp height: _________ centimetres

Trial Results:

Trial 1 time: _______ seconds

Trial 2 time: _______ seconds

Trial 3 time: _______ seconds

Average time: _______ seconds

Calculated speed: _______ metres per second

6. Show your speed calculation work:

7. Describe what happened to the speed when you changed the ramp height:

🔬 Part 3: Analysis and Reflection

8. Explain how potential energy is transformed into kinetic energy in this experiment:

9. What force slows down the object as it rolls along the floor? How does this affect the motion?

10. If you wanted to make the object go faster, what changes could you make to your setup? Give two suggestions:
