What is displacement divided by time?

• Position

• Force

• Velocity

• Acceleration

What does a straight horizontal line on a position vs. time graph indicate?

• No movement

• Acceleration

• Constant velocity

• Changing velocity

How can you determine if an object is accelerating from a position vs. time graph?

• By checking if the line is curved

• By checking if the line has a positive slope

• By checking if the line has a negative slope

• By checking if the line is straight and horizontal

What does a positive slope on a position vs. time graph indicate?

• The object is accelerating

• The object is moving to the left

• The object is moving to the right

• The object is not moving

What does a constant velocity imply about the net force acting on an object?

• There is a net force acting on the object

• The net force is zero

• The object is accelerating

• The object is decelerating

What does a curved line on a position vs. time graph indicate?

• Acceleration

• Deceleration

• No movement

• Constant velocity

What is the acceleration due to gravity approximately equal to?

• 10 meters per second squared

• 5 meters per second squared

• 15 meters per second squared

• 9.8 meters per second squared
