Section 1

Question Answer
WeightForce of gravity
WeightDecreases as you move away from the Earth
MassInertia
Constant VelocityNet force and acceleration is zero
Zero VelocityNet force and acceleration is zero
Weightmass x acceleration
Velocity-Time GraphSlope is acceleration
CentripetalCenter
Unbalanced ForceNot in equilibrium
Unbalanced ForceMust produce acceleration
Distance-Time GraphSlope is elocity
Equilibrium ForceEqual in magnitude
Equilibrium ForceOpposite to the resultant vector
MomentumConserved in collisions
MagnitudeHow large a vector is
