Understanding Rest and Motion

What determines if a body is at rest?

• Its position relative to a reference frame

• Its speed

• Its mass

• Its color

How is motion defined in kinematics?

• A body changing its position relative to a reference frame

• A body decelerating

• A body remaining stationary

• A body accelerating

When sitting inside a moving bus, how are you at rest?

• Relative to the sky

• Relative to the trees outside

• Relative to the bus
