Question

1. a) The position of an object has a linear relation (non-zero slope) with respect to time. How would you expect the acceleration to vary with time?

parabolic relationship linear relationship (non-zero slope)

linear relationship (zero-slope)

exponential relationship

hyperbolic relationship

b) When evaluating a graph that plots v(t), what does the area contained under the function between two points of time represent?

acceleration

change in acceleration

position

change in position

change in velocity

c) The acceleration of an object has a linear relation (zero slope) with respect to time. How would you expect the position to vary with time?

parabolic relationship

linear relationship (non-zero slope)

linear relationship (zero-slope)

exponential relationship

a,b, or c

d) A linear slope (negative) for velocity indicates

a constant (negative)

acceleration a constant (positive)

acceleration zero acceleration a parabolic (positive)

acceleration a parabolic (negative) acceleration

e) When evaluating a graph that plots r(t), what does the slope between two points of time represent?

instantaneous velocity

average position

average velocity

instantaneous position

average acceleration
