Term
 Gravitation pull is greater between two objects that have
Definition
 greater MASSES
Term
 Mass
Definition
 is a measure of the amount of matter
Term
 If a student has a weight of 420 N on Earth what is the student's weight on the moon
Definition
 70 N
Term
 Law of Universal Gravitation says
Definition
 gravitiational force is related to mass and distance
Term
 Examples of Projectile Motion
Definition
 path of a leaping frog, arrow through the air, pitched baseball
Term
 If a tennis ball, a solid rubbe ball, and a solid steel ball were dropped at the same time from the same height which would hit the ground first
Definition
 all three balls would hit at the same time - assuming there is no air resistance.
Term
 Which has the most acceleration an empty shopping cart pushed with a hard force or a full shopping cart pushed with a hard force
Definition
 an empty shopping cart pushed with a hard force.
Term
 A crumpled piece of paper hits the ground before a flat sheet of paper because
Definition
 there is more air resistance against the flat paper
Term
 Orbital motion
Definition
 is a combination of forward motion and free fall
Term
 a 5kg object has less inertia than an object with a mass of
Definition
 6 kg
Term
 According to Newtons first law of motion a moving object that is not acted on by an unbalanced force will
Definition
 remain in motion
Term
 The forces between a bat and ball aare an example of an
Definition
 action reaction force pair
Term
 A ball thrown horizontally will follow a path that is curved downward because
Definition
 the ball is accelerated by gravity in the vertical direction only
Term
 Mass
Definition
 a measure that does not change when an object's location changes
Term
 Weight
Definition
 the measure of gravitational force exerted on an object
Term
 Gravity
Definition
 the force of attraction between objects
Term
 Terminal Velocity
Definition
 this is the constant velocity of a falling object wehn the force of gravity is balanced by the force of air resistance.
Term
 Newton's second law of motion
Definition
 the acceleration of an object depends on the mass of the object and the amount of force applied.
Term
 Newoton's first law of motion
Definition
 An object at rest remains at rest, and an object in motion remains in motion at a constant speed and in a stright line unless acted on by an unbalanced force
Term
 Inertia
Definition
 all objects tend to resist any change in motion
Term
 Newton's third law of motion
Definition
 all forces act in pairs
