Newton`s Second Law
... • According to the second law of motion, when a ball has centripetal acceleration, the direction of the net force on the ball also must be toward the center of the curved path. • The net force exerted toward the center of a curved path is called a centripetal force. ...

Lesson 2 - Choteau Schools
... Lesson 2: Newton’s First Law • An object’s motion can only be changed by unbalanced forces. • According to Newton’s first law of motion, the motion of an object is not changed by balanced forces acting on it. • Inertia is the tendency of an object to resist a change in its motion. ...

FE REV Q
... If the velocity increases at a constant rate, and the car travels in a straight line, what is the magnitude of the acceleration? What is the car's displacement at the end of that 5 s interval? The car's mass is 1500 kg. Your friend pushes with a force of 200 N. Describe the horizontal forces acting ...

Conservation of angular momentum
... When a diver accelerates down from the 10m tower it takes her less than two seconds to hit the water. In flight, the diver’s angular momentum remains constant. Her angular momentum is determined by her rate of spin, her mass, and the distribution of her mass. What causes the diver to spin faster? Sh ...
