Centripetal Acceleration

Newton's 2nd law
,
a = net F / m
, tells us that net force and its corresponding acceleration are always in the same direction. Remember that both force and acceleration are vector quantities. But force and acceleration are not always in the direction of velocity, another vector quantity.
Refer to the following information for the next three questions.
You're in a car at a traffic light. The light turns green and the driver "steps on the gas."
Your body lurches
forward.
not at all.
backward.
The car accelerates
forward.
not at all.
backward.
The force on the car acts
forward.
not at all.
backward.
The sketch shows the top view of the car.
Note the directions of the
velocity and acceleration vectors
Refer to the following information for the next three questions.
You're driving along and approach a stop sign. The driver steps on the brakes.
Your body lurches
forward.
not at all.
backward.
The car accelerates
forward.
not at all.
backward.
The force on the car acts
forward.
not at all.
backward.
The sketch shows the top view of the car.
Draw vectors for velocity and acceleration.
Refer to the following information for the next three questions.
You continue driving, and round a sharp curve to the left at constant speed.
Your body lurches
inwards towards the left.
not at all.
outwards towards the right.
The car accelerated
inwards towards the left.
not at all.
outwards towards the right.
The force on the car acts
inwards towards the left.
not at all.
outwards towards the right.
The sketch shows the top view of the car.
Draw vectors for velocity and acceleration.
In general, the directions of the lurch and the acceleration, and therefore the firections of the lurch and the force, are
the same.
not related.
opposite.
Refer to the following information for the next two questions.
The whirling stone's direction of motion keeps changing.
If it moves faster, its direction changes
faster.
slower.
This indicates that as speed increases, acceleration
increases.
decreases.
remains the same.
Refer to the following information for the next two questions.
Consider whirling the stone on a shorter string-that is, of smaller radius.
For a given speed, the rate that the stone changes direction is
less.
more.
the same.
This indicates that as the radius decreases, acceleration
increases.
decreases.
remains the same.
