A change in velocity over a given time period.
A situation in which the forces acting upon an object are in balance.
The product of mass multiplied by acceleration.
The tendency of an object in motion to remain in motion, and of an object at rest to remain at rest.
A measure of inertia, indicating the resistance of an object to a change in its motion—including a change in velocity.
For an object experiencing torque, moment arm is the distance from the pivot or balance point to the vector on which force is being applied. Moment arm is always perpendicular to the direction of force.
The rate at which the position of an object changes over a given period of time.
The product of momentarm multiplied by force.
A quantity that possesses both magnitude and direction. By contrast, a scalar quantity is one that possesses only magnitude, with no specific direction.
The speed of an object in a particular direction.
A measure of the gravitational force on an object; the product of mass multiplied by the acceleration due to gravity.
