2. Newton’s third law of motion involves a force pair acting on an object.

3. An car moving with a constant speed a net force greater than zero

4. What two things can be happening if an object has a net force of zero?
It can be moving at a constant speed or it can be at rest.

5. What is inertia? Measurement of electrical resistance
A ratio between mass and velocity
Resistance to motion or change
The speed at which an object falls
All of the above

6. Which of Newton’s laws involves an action reaction pair of forces that are equal in strength but move in opposite directions?
Newton’s first law
Newton’s second law
Newton’s third law
Newton’s fourth law
None of the above

7. What is the net force acting on the ball?

8. What happens to the inertia of an object if the mass decreases?
The inertia also decreases.

9. What do we call the sum of all the forces acting on an object?
Net forces

10. A swimmer races across the pool in a competition
A swimmer races across the pool in a competition. What are the action reaction pair in this situation?
The force of the swimmer’s hands pushing on the water and the water pushing back on the swimmer’s hand.

11. They will move away from each other.
Two girls are standing still on inline skates. One of the girls pushes the other from behind. What will happen?
They will move away from each other.

12. Car B will accelerate faster than car A
You hold two toy cars together with a compression spring between them. Car A has more mass than Car B. What will happen to them when you let go of them at the same time?
Car B will accelerate faster than car A

13. A car is moving down a road. It suddenly decreases speed
A car is moving down a road. It suddenly decreases speed. What caused this to happen?
Two equal but opposite forces acted on it.
It was moved by two opposite forces
It is moved by unbalanced forces
None of the above
All of the above

14. A 250 N force makes an object accelerate at 25 m/s/s

10 Kg
225 Kg
275 Kg
6250 Kg
None of the above

The speed at which an object falls
All of the above

16. Two Sumo wrestlers push against each other in a match
Two Sumo wrestlers push against each other in a match. At first, wrestler A gets pushed backwards two steps, but then they stop moving even though they are still pushing against each other. Why did this happen?
At first the forces are unbalanced, then wrestler B pushes with a greater force until the forces are balanced.

17. His speed is decreasing
A jogger runs a race. He passes markers every 100 yards. Over time, it takes him longer to reach the markers. What is his motion?
His speed is decreasing
