A fly riding on the blade of a fan spinning at a constant speed is not accelerating

The acceleration of an object in uniform circular motion always points toward the center of the circle.

Centrifugal force is a center-seeking acceleration

When an object moves in a circle at a constant speed, the net force toward the center of the circle is the centripetal force.

The outside edge of a spinning compact disc is moving at a higher velocity than an inside track on the disc

Ellipses have only one focus

Gravity is a contact force.

When an object is moving with uniform circular motion, the object's tangential speed

The centripetal force on an object in circular motion is

A ball is whirled on a string, then the string breaks. What causes the ball to move off in a straight line?

When calculating the gravitational force between two extended bodies, you should measure the distance

Newton's law of universal gravitation

The gravitational force between two masses is 36 N. What is the gravitational force if the distance between them is tripled?

When a car makes a sharp left turn, what causes the passengers to move toward the right side of the car?

Two small masses that are 10.0 cm apart attract each other with a force of 10.0 N. When they are 5.0 cm apart, these masses will attract each other with what force?
