Which of the following best describes distance?

• The change in position from start to finish in a straight line

• The total length of the path traveled

• Speed in a given direction

• The rate of change of velocity

Which word represents a quantity that has magnitude but no direction?

• Vector

• Displacement

• Scalar

• Velocity

Which term is defined as “speed in a given direction”?

• Acceleration

• Velocity

• Vector

• Distance

What is the correct definition of acceleration?

• Distance traveled per unit of time

• The change in velocity over time

• The amount of space between two objects

• The force acting on an object

Free fall occurs when:

• An object moves at a constant velocity

• Only gravity is acting on the object

• An object is thrown horizontally

• Friction and air resistance are balanced
