Read each question carefully and answer to the best of your ability. Show your work for any calculations.
1. What happens to an object when the net force acting on it is zero?
It accelerates.
It slows down.
It remains at rest or continues at a constant velocity.
It changes direction only.
2. Which of the following is the unit for acceleration?
Newtons (N)
Meters (m)
Meters per second (m/s)
Meters per second squared (m/s²)
3. Newton's First Law of Motion states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an force.
4. The formula for calculating force is Force = mass × .
5. If a large force acts on a small mass, the acceleration will be small.
True
False
6. Friction is a force that always opposes motion.
True
False
7. Describe the relationship between net force, mass, and acceleration as stated in Newton's Second Law of Motion.
8. A car with a mass of 1000 kg accelerates at 2 m/s². Calculate the net force acting on the car.
Match the term on the left with its definition on the right.
9. Net Force
a. The rate at which velocity changes over time.
10. Acceleration
b. The overall force acting on an object.
11. Inertia
c. The tendency of an object to resist changes in its state of motion.
