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
