Lesson: Circular Motion

Force of gravity is inversely proportional to

If I double the mass of one object without changing anything else, What would happen to the gravitational force between that object and any other object?

What happens to Gravitational force if I double both of the masses but don't change their distance?

Find the distance between two objects whose masses are m₁ = 4,500 kg, and m₂ = 8,700 kg; if the gravitational force between them is F = 2.0 x 10^-8 N.

The rotational equivalent to x (displacement), v (velocity) and a (acceleration) are?

Which of the following is NOT a unit of angular velocity?

A bug on a spinning record will make more turns per minute if it is located toward the center of the record.

Which represents the acceleration of the ball? The ball is moving counter-clockwise.

Where should you go on a merry go round to go fastest?

If mass increases force will....

If radius increases force will....

If velocity increases force will....

A dog sits 1.50 m from the center of a merry-go-round and revolves at a tangential speed of 1.80 m/s. If the dog’s mass is 18.5 kg, what is the magnitude of the centripetal force on the dog?

Earth will travel fastest in its orbit when
