1. QuestionMultiple choice

Ignoring air resistance, what is the acceleration of a dropped object near Earth?

Please select an answer first.

Correct answer: A

The correct answer is 9.8 m/s29.8\,\text{m/s}^2 downward.

  1. Identify the motion model: Determine whether the problem describes position, displacement, velocity, acceleration, a graph, a vector, or a specified motion scenario.
  2. Apply the kinematics relationship: Gravity gives all freely falling objects the same downward acceleration near Earth's surface when air resistance is ignored.
  3. Check direction and units: The correct answer is 9.8 m/s29.8\,\text{m/s}^2 downward.

Gravity gives all freely falling objects the same downward acceleration near Earth's surface when air resistance is ignored.

2. QuestionMultiple choice

A ball is thrown upward. At its highest point, what is its acceleration?

Please select an answer first.

Correct answer: B

The correct answer is Downward gravitational acceleration.

  1. Identify the motion model: Determine whether the problem describes position, displacement, velocity, acceleration, a graph, a vector, or a specified motion scenario.
  2. Apply the kinematics relationship: At the highest point the instantaneous velocity is zero, but gravity continues to provide downward acceleration.
  3. Check direction and units: The correct answer is Downward gravitational acceleration.

At the highest point the instantaneous velocity is zero, but gravity continues to provide downward acceleration.

3. QuestionMultiple choice

What is the vertical velocity of a projectile at its highest point?

Please select an answer first.

Correct answer: C

The correct answer is Zero.

  1. Identify the motion model: Determine whether the problem describes position, displacement, velocity, acceleration, a graph, a vector, or a specified motion scenario.
  2. Apply the kinematics relationship: The upward vertical velocity decreases to zero at the top before becoming downward.
  3. Check direction and units: The correct answer is Zero.

The upward vertical velocity decreases to zero at the top before becoming downward.

4. QuestionMultiple choice

For an ideal projectile launched horizontally, which quantity remains constant?

Please select an answer first.

Correct answer: D

The correct answer is Horizontal velocity.

  1. Identify the motion model: Determine whether the problem describes position, displacement, velocity, acceleration, a graph, a vector, or a specified motion scenario.
  2. Apply the kinematics relationship: With no horizontal force, horizontal acceleration is zero and horizontal velocity remains constant.
  3. Check direction and units: The correct answer is Horizontal velocity.

With no horizontal force, horizontal acceleration is zero and horizontal velocity remains constant.

5. QuestionMultiple choice

What determines the time an ideal horizontal projectile takes to reach the ground?

Please select an answer first.

Correct answer: A

The correct answer is Its vertical drop and gravitational acceleration.

  1. Identify the motion model: Determine whether the problem describes position, displacement, velocity, acceleration, a graph, a vector, or a specified motion scenario.
  2. Apply the kinematics relationship: Vertical motion determines fall time; horizontal speed changes range but not time for the same height.
  3. Check direction and units: The correct answer is Its vertical drop and gravitational acceleration.

Vertical motion determines fall time; horizontal speed changes range but not time for the same height.

6. QuestionMultiple choice

Why do two objects dropped from the same height land together in an ideal model?

Please select an answer first.

Correct answer: B

The correct answer is They have the same gravitational acceleration and initial vertical velocity.

  1. Identify the motion model: Determine whether the problem describes position, displacement, velocity, acceleration, a graph, a vector, or a specified motion scenario.
  2. Apply the kinematics relationship: With the same initial vertical conditions and equal gravitational acceleration, their vertical motions match.
  3. Check direction and units: The correct answer is They have the same gravitational acceleration and initial vertical velocity.

With the same initial vertical conditions and equal gravitational acceleration, their vertical motions match.

7. QuestionMultiple choice

A projectile's horizontal range is the product of what quantities?

Correct answer: C

The correct answer is Horizontal velocity and time of flight.

  1. Identify the motion model: Determine whether the problem describes position, displacement, velocity, acceleration, a graph, a vector, or a specified motion scenario.
  2. Apply the kinematics relationship: Horizontal displacement follows Δx=vxt\Delta x=v_x t when horizontal velocity is constant.
  3. Check direction and units: The correct answer is Horizontal velocity and time of flight.
