C11S2 - Section 2 Quiz Practice

If a car is going around a corner maintaining the same speed, it is experiencing ...

• constant velocity
• centripetal acceleration
• negative acceleration
• no acceleration

Velocity and acceleration are vectors.  That means that 

• they are specified only by their magnitude (m/s, m/s²)
• they are specified by only their direction.
• they are specified by both their magnitude and their direction.
• they always point in the direction of the movement.

A bicyclist slowing down to go around a corner is accelerating.

• True
• False

A graph of velocity vs time for an object moving at a constant velocity would have a straight line ...

• with a positive, upward slope.
• with a negative, downward slope
• and a curved line
• that is horizontal

What does a velocity vs time graph with a line slanted down (negative slope) indicate.

• negative acceleration, deceleration, slowing down
• positive acceleration, speeding up
• no acceleration just change in speed

The slope of a velocity vs time graph is the ____________ of an object.

• velocity
• acceleration
• direction
• displacement
