AP Physics 1 Facts

On a position time graph, how do you determine how far an object is from where it started (or the motion detector)?

• Slope (steepness)

• Vertical axis

• Slope of tangent

• Slope of secant

On a position time graph, how do you determine how fast an object is moving?

• Slope of secant

• Vertical axis

• Slope (steepness)

• Slope of tangent

On a curved position time graph, how do you determine instantaneous speed?

• Slope of secant

• Vertical axis

• Slope (steepness)

• Slope of tangent

On a curved position time graph, how do you determine average speed?

• Slope of tangent

• Vertical axis

• Slope (steepness)

• Slope of secant

On a position time graph, how do you determine which way the object is moving?

• Look at which way the position-time graph is sloped.

• Away from the x-axis is away from the start (motion detector)

• Toward the x-axis is toward the start (motion detector) or backwards

• Vertical axis (magnitude only)

On a velocity time graph, how do you determine how fast an object is moving?

• Below axis is + direction (forward)

• Above axis is + direction (forward)

• Vertical axis (magnitude only)

• Area under curve

On a velocity time graph, how do you determine which way the object is moving?

• Above axis is + direction (forward)

• Below axis is - direction (backwards)

• Vertical axis (magnitude only)

• Area under curve

On a velocity time graph, how do you determine how far an object travels?

• Vertical axis

• Slope (steepness)

• Area under curve

• Final position (the area gives you Δx, not final position)

What is the slope of a velocity-time graph?

• Final position (the area gives you Δx, not final position)

• Acceleration

• Vertical axis

• Slope of secant

What is acceleration?

• Change in velocity per time (Δv/t)

• Slope of secant

• Area under curve

• Vertical axis
