Physics Concepts: Motion and Measurement

The SI unit of length is the meter (m)

• True

• False

Velocity has both magnitude and direction.

• True

• False

What car odometer measure

• Total displacement of all past trips

• Total distance of all past trips

• Distance of most recent trip

• Displacement of most recent trip

What is The Equation For Acceleration?

• Time/Velocity

• Displacement/time

• Change In Velocity/ Time

• Speed/Time

Which velocity/time graph shows a vehicle slowing to a stop?

• (1)

• (2)

• (3)

• (4)

• (5)

An airplane accelerates down a runway at 3.20 m/s^2
for 8 s until it finally lifts off the ground.
Determine the velocity at take-off.

• 0.4 m/s
• 25.6 m/s
• 2.5 m/s

A cheetah travels 75 m in 3 s. What is her velocity over the interval?

• 225 m/s
• 25 m/s 
• 0.04 m/s

A roller coasters accelerates from an initial velocity of 6.0 m/s to a final velocity of 70 m/s over 4 seconds.  What's the acceleration?

• 24 m/s²
• 18 m/s²
• 16 m/s²
• 16 m/s
