Name Reading Science – Newton`s Laws and Roller Coasters In
... The mass of your body and the coaster cars is constant while the amount of force changes due to changes in acceleration. The changes in acceleration are due mostly to friction. Newton’s third law of action-reaction, states that for every action, there is an equal and opposite reaction. This means th ...

Action and Reaction on Different Masses
... Newton’s third law describes the relationship between two forces in an interaction. • One force is called the action force. • The other force is called the reaction force. • Neither force exists without the other. • They are equal in strength and opposite in direction. • They occur at the same time ...

... Mass: Property of a body of fluid that is a measure of its inertia or resistance to a change in motion. It’s also a measure of the quantity of fluid. Mass does not change with the body’s position, movement or alteration of its shape unless material is added or removed. Weight: Gravitational force ac ...

... B) No, because the force and the displacement of the object are perpendicular. C) Yes, since a force acts and the object moves, and work is force times distance. D) Yes, since it takes energy to turn an object. 40) A 3.0-kg object moves to the right at 4.0 m/s. It collides head-on with a 6.0-kg obje ...

Momentum and Impulse notes
... What does momentum and impulse have to do with each other? Momentum = mv If velocity changes, momentum changes, and acceleration (either + or –) occurs But we know: 1. for acceleration to occur, a force has to be applied. 2. If a given force is applied over a longer time, more acceleration occurs. ...
