Post Test
Directions: Read the questions carefully. Write the letter of the correct answer on your answer sheet.
1. What is the least number of systems that can display action-reaction forces?
D. 4
A. 1
3
В.
C.
2.
2. Car A, having a mass of 450 kg, was involved in a collision accident with Car B, which had a mass of 650
kg. What could be said about the force experienced by car with the higher mass with respect to the lighter
car?
A. Both cars experience the same amount of force.
B. The magnitude cannot be determined from this data.
C. Car B experiences a greater magnitude of force than Car A.
D. Car A experiences a greater magnitude of force than Car B.
3. As stated in Newton's third law of motion, what happens when object A exerts force to object B?
A. Object B gets pushed.
B. Object B remains to be at rest.
C. Object A exerts s reaction force to object B.
D. Object B exerts a reaction force back to the object A.
4. Which is NOT true about action-reaction forces?
A. They occur in a single system.
B. They are opposite in direction.
C. They are equal in magnitude.
D. They act on two different interacting systems.
5. A car and a truck collide head-on. The car gets pushed back farther than the truck. Which statement best
explains the incident?
A. The truck exerted greater force than the car.
B. The car exerted greater force than the truck.
The action-reaction forces are unequal, which lead to a greater push to the car.
