YTQ: Motion and Acceleration Concepts

What is the term for a point used to describe the motion of an object?

• Reference point

• Starting line

• Fixed position

• Frame of reference

What measures how fast an object is moving?

• Velocity

• Acceleration

• Speed

• Direction

What are the common units for measuring speed?

• Meters per second (m/s)

• Meters per second squared (m/s^2)

• Newtons (N)

• Kilograms (kg)

Which type of quantity only has a magnitude and no direction?

• Vector quantity

• Scalar quantity

• Directional quantity

• Motion quantity

What is a measure of both an object's speed and its direction of motion?

• Acceleration

• Speed

• Velocity

• Distance

Which term describes a quantity that has both magnitude and direction?

• Scalar quantity

• Vector quantity

• Speed

• Acceleration

What is the rate at which an object's velocity changes?

• Speed

• Distance

• Acceleration

• Time

What are the units used to measure acceleration?

• Meters per second (m/s)

• Meters (m)

• Meters per second squared (m/s^2)

• Seconds (s)

An object can have a constant speed, but its velocity can change if what happens?

• Its mass increases

• Its color changes

• Its direction of motion changes

• It stops moving

In what two ways can an object experience acceleration?

• By changing its mass or its volume

• By changing its color or its shape

• By changing its speed or its direction

• By changing its height or its width
