Motion, Distance, and Energy Quiz for 7th Grade

What is the key difference between distance and displacement?

• Distance is always positive, displacement can be zero
• Distance measures total path, displacement measures direct path
• Distance has no direction, displacement has direction
• Distance is shorter than displacement

If you walk around a circular track and return to your starting point, what would your displacement be?

• Equal to the track's circumference
• Zero
• Maximum distance traveled
• Infinite

Which formula correctly calculates speed?

• Speed = Time ÷ Distance
• Speed = Distance × Time
• Speed = Distance ÷ Time
• Speed = Time + Distance

What determines an object's potential energy?

• Speed and direction
• Mass and acceleration
• Weight and height
• Force and time

In the work formula Work = Force × Displacement, what does displacement represent?

• Total distance traveled
