3 cards from this section. Quick, good the night before a test.
What is the definition of circular motion?
Think about the path or trajectory of an object.
What force keeps an object moving in circular motion?
This force always points towards the center of the circle.
What is centripetal force?
Think about where this force is directed.
True or False: Centripetal acceleration occurs when the speed of an object in circular motion changes.
Consider the object's speed versus its direction.
A satellite is orbiting the Earth at an altitude of 300 km. Determine the centripetal force acting on the satellite if its mass is 500 kg.
Remember to consider the radius from the center of the Earth, not just the height.
A car of mass 1000 kg reliably turns on a circular track of radius 50 m at a speed of 20 m/s. Calculate the required centripetal force.
Think about how much force is necessary to keep it moving along the curve.
