B
C
D
A car is rounding a curve as shown in the diagram. Which arrow correctly shows the direction of the centripetal force keeping the car in circular motion?
A
B
C
D
Why do sharp turns in roads have reduced speed limits posted?
The lower the speed the lower centripetal force.
The lower the speed the higher centripetal force.
The lower the speed the larger the radius.
Speed limits aren't reduced on sharp turns.
If car A and car B are both traveling at the same speed, which will require a higher centripetal force?
Car A
Car B
They have the same centripetal force
A bola is an old hunting instrument. If three rocks with a combined mass of 0.75 kg are spun at a speed of 20 m/s with a radius of 0.5 m, how much centripetal force is required to keep them spinning.
600 N
45 N
30 N
400 N
moving or tending to move toward a center...
centripetal force
centrifugal force
Tangent
Curvature
Why does velocity happen when going in a circle even if you are going the same speed?
The direction around the circle changes at every point.
Velocity does not change
Because direction is the same around the circle
Neither
If velocity increases force will....
increase because they have a direct relationship
increase because they have a inverse relationship
decrease
both
