Practice AP Physics C: Mechanics Dynamics: Force and Newton's Laws of Motion in the app →Kinematics only describes how objects move. The study of the forces that cause motion is:A force is a push or pull that has both magnitude and direction, so it is a:A diagram showing a body as a single point with only the external forces acting on it is a:A stretched spring pulling back to its relaxed shape exerts a:A hockey puck glides far on an air table because friction is nearly gone. This illustrates Newton's:The property of a body to remain at rest or keep moving at constant velocity is called:Inertia is measured by an object's:A kilogram of cotton balls and a kilogram of gold have:Newton's second law states acceleration is directly proportional to net external force and inversely proportioThe newton is the force needed to accelerate a 1 kg system at:The weight of a 1.0 kg object on Earth is about:On the Moon, where g is 1.625 m/s squared, a 1.0 kg mass weighs about:A net force of 51 N pushes a 24 kg lawn mower. Its acceleration is about:Whenever one body exerts a force on a second, the first experiences an equal and opposite force. This is NewtoA swimmer pushes on the pool wall and accelerates away. The two equal and opposite forces do not cancel becausA rocket moves forward because expelled gas exerts a forward reaction force called:The support force perpendicular to a surface of contact is called the:On a frictionless incline at angle theta, the acceleration of any mass is:A 5.00 kg mass hangs at rest from a rope. The tension in the rope is:A 70 kg tightrope walker makes a wire sag by 5 degrees. The tension in the wire is about:Forces that appear only because an observer is in an accelerating frame of reference are:Earth's rotation is slow enough that Earth is nearly a:
