🚀 Part 1: Multiple Choice & True/False

Instructions: Choose the best answer for each question. Circle the letter for multiple choice questions.

1. What is the unit used to measure distance?

a) Seconds

b) Metres

c) Kilograms

d) Degrees

2. Which of the following affects the motion of objects on Earth?

a) Gravity

b) Friction

c) Air resistance

d) All of the above

3. True or False: The Earth rotates on its axis once every 24 hours.

True

False

4. True or False: All planets in our solar system orbit the Sun in the same direction.

True

False

5. What causes day and night on Earth?

a) Earth's orbit around the Sun

b) Earth's rotation on its axis

c) The Moon's position

d) Distance from the Sun

✏️ Part 2: Fill in the Blanks & Short Answers

6. Fill in the blanks:

The force that pulls objects towards the centre of Earth is called ________________.

7. Fill in the blanks:

It takes Earth approximately __________ days to complete one orbit around the Sun.

8. Fill in the blanks:

When an object is in motion, it has __________ energy.

9. Short Answer: Explain the difference between speed and velocity. Give an example.

10. Short Answer: Describe what happens to the motion of a rolling ball when it encounters friction. Why does this occur?

📋 Answer Key

1. b) Metres

2. d) All of the above

3. True

4. True

5. b) Earth's rotation on its axis

6. gravity

7. 365 (or 365.25)

8. kinetic

9. Speed is how fast something moves (scalar), while velocity includes both speed and direction (vector). Example: A car travelling 60 km/h has speed, but a car travelling 60 km/h north has velocity.

10. Friction opposes the motion of the rolling ball, causing it to slow down and eventually stop. This occurs because friction converts the ball's kinetic energy into heat energy.
