📚 Part 1: Definitions and Concepts

1. Speed is the rate of change of _______________.

2. Displacement includes both _______________ and _______________.

3. Which statement best describes velocity?

How fast an object moves

How far an object travels

Speed with direction

The force applied to an object

4. Acceleration is:

The change in velocity over time

The same as speed

Always positive

Measured in meters

5. Write the formula for calculating speed:

Speed = ________________ ÷ ________________

🧮 Part 2: Calculations

6. A ball rolls 20 meters north in 4 seconds. Calculate:

a) Speed: ________________ meters per second

b) Velocity: ________________ meters per second ________________

7. A car accelerates from 0 m/s to 15 m/s in 5 seconds. What is the acceleration?

Acceleration = ________________ m/s²

8. If a 3 kg ball accelerates at 4 m/s², what is the force applied? (Use F = m × a)

Force = ________________ Newtons

9. A student walks 30 feet east, then 40 feet north. What is the total displacement?

Displacement = ________________ feet at ________________ degrees

🚗 Part 3: Real-World Applications

10. A toy car travels around a circular track at a constant speed of 2 m/s. Explain why the car is still accelerating even though its speed doesn't change.

11. Compare the motion of two objects:

Object A: Moves 10 meters in 2 seconds going east

Object B: Moves 10 meters in 2 seconds going west

Do they have the same speed? _______ Do they have the same velocity? _______

Explain your reasoning:

12. A 50 kg student pushes a 20 kg desk with a force of 60 Newtons. What is the acceleration of the desk? Show your work.
