 Which of Newton's laws states that an object resists change in motion unless acted upon by an external force? NEWTON'S FIRST LAW OF MOTION Which of Newton's laws addresses the attraction between two objects as a result of mass and distance? NEWTON'S LAW OF UNIVERSAL GRAVITATION Which of Newton's laws states the for every action force there is a reaction force that is equal and opposite? NEWTON'S THIRD LAW OF MOTION Which of Newton's laws addresses single objects in motion? FIRST AND SECOND LAWS OF MOTION Do action-reaction forces act on the same or separate objects? SEPARATE OBJECTS Describe the strength and direction of action-reaction forces. EQUAL STRENGTHS and OPPOSITE DIRECTIONS If you throw a ball, what is the action force? THE PUSH OF YOUR HAND ON THE BALL. If you throw a ball, what is the reaction force? THE PUSH OF THE BALL ON YOUR HAND. Why don't action-reaction forces always cancel each other out? THEY ACT ON DIFFERENT OBJECTS The backward acceleration from a reaction force is called RECOIL What two factors affect recoil? SPEED and MASS The mass of an object multiplied by its speed (or velocity) is called MOMENTUM. The equation for momentum is p = mv The symbol for momentum is p The symbol for mass is m The symbol for velocity is v The unit for velocity is m/s The unit for mass is kg The unit for momentum is kg.m/s Can the unit for momentum be written as a Newton? NO - a Newton has seconds squared in the denominator What law states that as long as interacting objects are not influenced by outside forces, the total momentum cannot change? LAW OF CONSERVATION OF MOMENTUM In regards to momentum, positive and negative refers to DIRECTION (+ is opposite to -) A shuttle resting on the launch pad, unable to move with out thruster engines on is an example of which of Newton's laws? FIRST LAW OF MOTION Which of Newton's laws is shown by a jet moving forward because the engine pushes the exhaust out backward? THIRD LAW OF MOTION Which law is shown by the fact that a greater force is needed to make a greater mass accelerate? SECOND LAW OF MOTION
