Physics Semester 1 Final

What is the displacement of an object at rest?

• 0 m
• 1 m
• 9.8 m
• 9.81 m

What is velocity?

• The total distance traveled by an object
• The distance from start to end, including the direction
• How fast an object travels
• The speed at which an object travels plus its direction

What is acceleration?

• It is the displacement.
• It is the velocity.
• It is the rate of change of the displacement.
• It is the rate of change of the velocity.
