1. If the same amount of braking force is applied to two moving objects, one with a low mass and one with a high mass, how will their change in velocity (deceleration) differ?
- A. The high-mass object will have a greater change in velocity.
- B. The low-mass object will have a greater change in velocity.
- C. Both objects will have the same change in velocity.
- D. Neither object will experience a change in velocity from the force.
2. A person finds it much harder to start pushing a shopping cart full of groceries than an empty one. This difficulty is primarily due to the full cart having greater...
- A. volume.
- B. inertia.
- C. velocity.
- D. potential energy.
3. Imagine the pod's thrusters were upgradeable. To safely stop the heavier-than-expected pod in the *same amount of time* as a standard pod, the thrusters would need to have...
- A. produced a smaller amount of force.
- B. weighed less to reduce the total mass.
- C. produced a greater amount of force.
- D. activated for a much shorter duration.
4. In physics, what does the term 'inertia' describe?
- A. The force an object exerts due to gravity.
- B. The speed at which an object travels through space.
- C. An object's resistance to any change in its state of motion.
- D. The amount of energy an object has because of its movement.
5. A student rolls a bowling ball and a tennis ball with the same initial velocity. If they apply an identical stopping force to both, which statement is true?
- A. The tennis ball will be harder to stop because it is smaller.
- B. The bowling ball will be harder to stop because its greater mass gives it more inertia.
- C. Both will be equally easy to stop because their initial velocity was the same.
- D. The bowling ball will stop faster because its weight helps create more friction.
6. According to Newton's Second Law of Motion, if a constant force is applied to an object and its mass is significantly increased, what will happen to its acceleration?
- A. The acceleration will increase proportionally.
- B. The acceleration will decrease.
- C. The acceleration will remain the same.
- D. The acceleration will become zero regardless of the force.
7. In the space pod scenario, new evidence revealed it was carrying a much heavier load than usual. In the context of a scientific investigation, what specific variable was altered by this new information?
- A. The net force acting on the pod's engines
- B. The pod's total mass
- C. The pod's initial velocity
- D. The gravitational field strength in the area
8. A space tug is designed to push satellites with a standard mass into a new orbit using a constant thrust from its engines. If the tug is mistakenly assigned to push a satellite that is twice as massive, what will be the effect on the satellite's motion compared to a standard satellite?
- A. It will accelerate twice as quickly because the engines must work harder.
- B. It will accelerate at half the rate of a standard satellite.
- C. It will accelerate at the same rate, but it will take longer to reach the target orbit.
- D. It will not move at all because the mass is too great for the engines to overcome.
9. Imagine two identical shopping carts, Cart A and Cart B. Cart A is empty, while Cart B is filled with heavy groceries. If you push both carts with the exact same force, which statement accurately describes the result?
- A. Both carts will accelerate at the same rate.
- B. Cart B will accelerate faster because it has more mass.
- C. Cart A will accelerate faster than Cart B.
- D. Cart B will have a higher final velocity regardless of how long you push.
10. The relationship between an object's mass and its acceleration, when a constant net force is applied, is best described as which of the following?
- A. A directly proportional relationship, where an increase in mass causes a proportional increase in acceleration.
- B. An exponential relationship, where acceleration increases with the square of the mass.
- C. An inversely proportional relationship, where an increase in mass causes a decrease in acceleration.
- D. An unrelated relationship, as mass and acceleration are independent variables in this context.
