Question | Answer |
---|---|
speeding up | if the net force acting on a moving object is in the direction that the object is moving, the object will speed up |
slowing down | if the direction of the net force on an object is opposite to the direction the object moves |
Newton's second law of motion | states that the acceleration of an object is equal to the net force acting on the object dividing by the object's mass |
circular motion | any motion in which an object is moving along a curved path |
centripetal force | in circular motion, a force that acts perpendicular to the direction of motion, toward the center of the curve |
