Forces and Motion
The definition of weight
What is a measure of the force of gravity on an object
Second Law of Motion
What is states that an object acted on by an unbalanced force will accelerate in the direction of the force with an acceleration equal to the force divided by the object's mass
Mass is a property of
What is matter
The definition of acceleration
What is change in velocity divided by the time it takes for the change to occur
First Law of motion (Law of inertia)
What is an object in motion stays in motion while an object at rest stays at rest
Weight can be zero if
What is no gravity acts upon an object
Mechanical Advantage
What is the number of times that the machine increases an input force
For every action
What is there is an equal and opposite re-action
Mass is a scalar quantity it has
What is magnitude
Force is measured in
What is Newtons
The formula for newtons second law of motion
What is F=ma
Mass does not change according to what
What is location
Third law of motion (Law of action and reaction)
What is for every action there is an equal and opposite reaction
Every object persists in its state of rest or uniform motion in a straight line unless
What is unless it is compelled to change that state by forces impressed on it
Weight is a vector quantity. It has magnitude and is directed toward the
What is the center of the Earth or other gravity well
