Circular Motion Math
What is the centripetal acceleration of an object moving at 10 m/s in a radius of 5 m?
20 m/s2
29.4 N
The type of force that causes an object to move in a circle.
What is Centripetal Force?
The equation used when solving for force of gravity when near Earth's surface.
What is F = mg?
This is the vertical acceleration of a cannonball after it has been shot out of a cannon.
What is -9.8 m/s2?
7.7 m/s
What is the force of gravity acting on a 1250 kg satellite orbiting 1.3x107 m from the center of earth? (Mass of Earth = 5.9x1024 kg)
2910.7 N
A perceived force that points outward from the center of circular motion.
What is centrifugal force?
The equation used when solving for the force of gravity when not near Earth's surface.
What is F = G(m1m2)/r2?
This is the horizontal acceleration of a cannonball that has just been shot out of a cannon.
What is zero?
What is the radius of a circular road in which the car experiences 1250 N of centripetal force, has a mass of 1000 kg and is moving at 12 m/s?
115 m
What is the acceleration due to gravity on Mars's surface? (Mass of Mars = 6.39x1023 kg, Radius of Mars = 3.3x106 m)
3.9 m/s2
This is the centripetal force which causes a car to move in a circle when traveling on a circular road.
What is Friction?
This is the symbol used to represent acceleration due to graivty.
What is g?
This is the definition for acceleration.
What is a change in velocity?
A 3 kg ball is being swung in a vertical circle. At the top of its motion, the tension in the string is equal to twice its weight. What is the centripetal force acting on the ball?
88.2 N
What is the velocity of a satellite that orbits with a radius of 2.4x106 m, and has a period of 9x105 s?
16.75 m/s
The direction in which centripetal force points when a ball attached to a string is at the bottom of its swing (vertically).
What is upwards?
This type of force can act on an object from a distance without needing to touch the object.
What is a field?
This is Newton's second law of motion.
What is F = ma?
What is the centripetal force of a 2000 kg car making its way around a 20o frictionless banked curve?
7133.8 N
What is the period of an 1800 kg satellite which orbits Earth with a radius of 7x106 m from its center? (Mass of Earth 5.9x1024)
5863.9 s
The centripetal force which causes a car to move in a circle when on a frictionless banked curve.
What is the X component of Normal Force?
This is the relationship between the force of gravity on two objects which are gravitationally attracted.
What is Equal and Opposite?
This is Newton's Third Law of Motion.
What is every action has an equal and opposite reaction?
