PTG, VTG review

Which of the following is a vector quantity?

• Speed

• Distance traveled

• Displacement

• Can only be positive

Which of the following quantities can only be positive?

• Displacement

• Velocity

• Speed

• Acceleration

Which statement is true about scalar quantities?

• They can be positive or negative

• They have both magnitude and direction

• They can only be positive

• They describe direction only

If a quantity can be positive or negative, what type of quantity is it most likely to be?

• Scalar

• Vector

• Both scalar and vector

• Neither scalar nor vector

Why is velocity considered a vector quantity?

• It only has magnitude

• It can only be positive

• It has both magnitude and direction

• It measures distance only

What does a position time graph represent?

• Displacement as a function of time

• Speed as a function of distance

• Acceleration as a function of mass

• Force as a function of velocity

On a position time graph, which variable is plotted on the x-axis?

• Displacement

• Time

• Speed

• Acceleration

Which axis represents the dependent variable in a position time graph?

• x-axis

• y-axis

• z-axis

• Both axes

Why is time considered the independent variable in a position time graph?

• Because it depends on displacement

• Because it is controlled or set in the experiment

• Because it is always constant

• Because it is measured in meters

Which section of the position time graph would represent an object that is not moving?

• A horizontal line

• A steep upward line

• A curved upward line

• A downward sloping line
