V
Concepts needed to describe motion?
Kinematics
The rate of change of velocity with respect to time?
Acceleration
Used if there is a string/pulley?
Tension
Friction while moving?
Kinetic Friction
The sum of forces acting on an object?
Net Force
The effect that force have on motion?
Dynamics
The motion of a body only when the force due to gravity is acting on the body?
Free fall
Force being applied to an object?
Applied Force
Friction keeps something from moving?
Static Friction
The greater the mass of a body, the less the body accelerates under applied force?
Mass of Inertia
Together, Kinematics and dynamics make up what?
Mechanics
A quantity that has both magnitude and direction?
Vector
Force that a surface imposes on a object?
Normal Force
Objects in motion stays in motion and object at rest stays at rest?
Newton's 1st law
Objects that are either at rest or moving with constant velocity?
Equilibrium
Displacement Divided by the elapse time
Average Velocity
An action exerted on an object which may change the objects state of rest or motion?
Force
Forces in opposing direction cancel?
Balance Force
Every action has a reaction?
Newton's 3rd law
Describes the force applied to an object over a parallel distances?
Work
How fast an object moves and the direction of motion at each instant?
Instantaneous Velocity
Opposes the direction of motion?
Friction
Forces in opposing direction do not cancel?
Unbalanced Force
Force is proportion to mass and acceleration?
Newton's 2nd law
How much work on energy is expanded over a given amount of time?
Power
