Circular Motion
Second Law says that when a net force acts on a mass, the net force causes acceleration in the same direction as the net force
Use Newton's laws to explain how you know that an object in uniform circular motion is being accelerated.
Newton's first law says it will move at a constant velocity unless a net force acts on it. An object in uniform circular motion has a changing velocity, therefore it has a net force
Use Newton's laws to explain how you know that an object in uniform circular motion must be experiencing a force.
Must be moving in a circle with a fixed radius & at a constant speed
What are the two conditions necessary for an object to be in uniform circular motion?
directly proportional to the square of the velocity
What is the relationship between the centripetal acceleration of an object in uniform circular motion and the object's velocity?
inversely proportional to the radius of rotation
What is the relationship between the centripetal acceleration of an object in uniform circular motion and the radius of the object's motion?
Velocity is a vector which means that includes direction and direction is changing
Why is a particle in uniform circular motion not moving at a constant velocity?
