Motion & Forces

Avery is walking from her home to the park. What is the definition of the distance she covers?

• The total path covered by an object

• The shortest path between two points

• The speed at which an object moves

• The direction of an object’s motion

Displacement is defined as:

• The total length of the path traveled

• The change in position of an object in a straight line

• The time taken to cover a distance

• The rate of change of velocity

Which of the following is an example of velocity?

• 50 meters

• 20 meters per second to the east

• 30 kilometers

• 5 seconds

Noah is driving his car on a highway. Speed is defined as:

• Distance traveled divided by time

• Displacement divided by time

• Change in velocity divided by time

• Acceleration multiplied by time

Abigail is running a race. What is the SI unit of speed she should use to measure her running speed?

• Meter

• Meter per second

• Kilometer

• Second

The formula for calculating velocity is:

• Velocity = Distance / Time

• Velocity = Displacement / Time

• Velocity = Acceleration / Time

• Velocity = Distance x Time

Lily walks 10 meters to the right to reach her friend's house and then walks 5 meters to the left to return home. What is her displacement?

• 5 meters to the right

• 5 meters to the left

• 15 meters to the right

• 15 meters to the left

Mason is driving his car and notices that the speedometer reading is increasing. Acceleration is defined as the rate of change of:

• Distance

• Speed

• Velocity

• Displacement

What is the SI unit of acceleration?

• Meter

• Meter per second

• Meter per second squared

• Second

Samuel is driving his car and accelerates from 0 m/s to 20 m/s in 5 seconds. What is the acceleration?

• 4 m/s²

• 5 m/s²

• 10 m/s²

• 20 m/s²
