Circular Motion (horizontal and vertical circles)

Front

What is velocity?

Back

Speed in a specific direction.

Front

What is centripetal acceleration?

Back

Acceleration toward the center of a curved or circular path.

Front

What two measurements are necessary for calculating speed?

Back

Distance and time.

Front

What is uniform circular motion?

Back

Motion of an object traveling at a constant speed in a circular path.

Front

What is the formula for centripetal acceleration?

Back

a_c = v^2 / r, where v is the speed and r is the radius.

Front

What is the relationship between speed and velocity?

Back

Speed is a scalar quantity, while velocity is a vector quantity.

Front

What is the direction of the net force acting on an object in uniform circular motion?

Back

Toward the center of the circular path.

Front

What happens to the centripetal acceleration if the speed of the object increases?

Back

Centripetal acceleration increases.

Front

What is the difference between linear speed and angular speed?

Back

Linear speed is the distance traveled per unit of time, while angular speed is the angle covered per unit of time.

Front

What is the effect of mass on centripetal force?

Back

Centripetal force increases with mass for a given acceleration.
