Centripetal Force

What best describes the relationship between the centripetal force and tangential velocity?

• They are equal in magnitude(amount) and point in the exact same direction

• They are equal in magnitude(amount) and point in opposite in directions

• They are equal in magnitude(amount) but they make a right angle(90 degrees)

• They can have different magnitudes(amounts) but they make a right angle(90 degrees)

Which is true about centripetal force and centripetal acceleration?

• The centripetal acceleration is always pointing toward the center of an orbit and the centripetal force is always pointing outward

• The centripetal acceleration is always pointing outward from the center of an orbit and the centripetal force is always pointing inward

• The centripetal acceleration is always pointing toward the center of an orbit and the centripetal force also pointing toward the center but in a totally different location

• The centripetal acceleration is always pointing toward the center of an orbit and the centripetal force also pointing toward the center and in the same exact location as the centripetal acceleration

A 10kg car travels at a constant speed of 20.0 m/s around a horizontal circular track. Which diagram correctly represent the direction of the car's velocity (v) and the direction of the centripetal force (Fc) acting on the car at a particular moment?

Centripetal acceleration and force always point

• in the direction of the object's motion

• in the opposite direction of the object's motion

• towards the center of the circle

• towards the outside of the circle

Which statement is true the image if A and B are on a spinning wheel?

• A has a greater tangential speed because it is closer to the center.

• B has a greater tangential speed because it is closer to the center.

• A has a greater tangential speed because it is further from the center.

• B has a greater tangential speed because it is further from the center.
