What is centripetal force?
💡 Hint: Think about where this force is directed.
True or False: Centripetal acceleration occurs when the speed of an object in circular motion changes.
💡 Hint: Consider the object's speed versus its direction.

Challenge Problems
Push your limits with advanced challenges
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.
💡 Hint: 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.
💡 Hint: Think about how much force is necessary to keep it moving along the curve.
