The property of things to resist changes in motion.
The quantity of matter in an object. More specifically, it is the measure of the inertia or sluggisshness that an object exhibits in response to any effort made to start it, stop it, deflect it, or change its state of motion in any way.
The unit of mass. One kilogram (kg) is the mass of 1 liter (L) of water at 4 degrees C
Simply stated, the force due to gravityon an object. More specifically, the gravitational force with which a body presses against a supporting surface.
Simply stated, a push or pull
The scientific unit of force
The combination of all forces that act on an object.
A quantity that specifies direction as well as magnitude.
The force that supports an object against gravity, often called the normal force.
The vector sum of forces acting on a nonaccelerating object equals zero
The resistive force that opposes the motion or attempted motion of an object through a fluid or past another object with which it is in contact.
The force of friction acting on an object due to its motion through air.
The distance traveled per time.
The speed of an object with specification of its direction or motion.
The rate at which velocity changes with time; the change in velocity may be in magnitude, or in direction, or in both. It is usually measured in m/s squared
The time that one's feet are off the ground during a vertical jump.
