centripetal force
... Second Law says that if an object is accelerating, there must be a net force on it. For an object moving in a circle, this is called the centripetal force. centripetal force points toward the center of the circle. ...

Laws of Motion Notes
... An object at rest remains at rest, and an object in motion stays in motion with constant velocity (constant speed in a straight line) unless the object experiences a net external force (unbalanced force) - Inertia is related to the amount of mass in an object o an object does not have to be moving t ...

... The initial momentum of the one-student system is nonzero. The initial momentum of the two-student system is zero. We're interested in the force exerted on one student, so we apply the Momentum Principle to a system consisting of one student. We can estimate Δt from the compression distance in the c ...

... Astronauts in space appear to be “weightless”. This statement is NOT true because gravity exists everywhere in the universe; it is the force of attraction between 2 objects due to mass. Astronauts in orbit experience apparent weightlessness because they are in free fall. The astronauts and vehicle ...
