|
force |
A push or pull that acts on an object.
|
|
|
newton
|
The force that causes a 1-kg mass to accelerate at a rate of 1 m/s/s.
|
|
|
net force
|
The overall force acting on an object after all the forces are combined.
|
|
|
friction
|
A force that opposes the motion of objects that touch as they move past each other.
|
|
|
static friction
|
The friction force that acts on objects that are not moving.
|
|
|
sliding friction
|
A force that opposes the direction of motion of an object as it slides over a surface.
|
|
|
rolling friction
|
The friction force that acts on rolling objects.
|
|
|
fluid friction
|
The force that opposes the motion of an object through a fluid.
|
|
|
air resistance
|
Fluid friction acting on an object moving through the air.
|
|
|
gravity
|
A force that acts between any two masses.
|
|
|
terminal velocity
|
The constant velocity of a falling object when the force of air resistance equals the force of gravity.
|
|
|
projectile motion
|
The motion of a falling object after it is given an initial forward velocity.
|
|
|
inertia
|
The tendency of an object to resist a change in its motion.
|
|
|
mass
|
A measure of the inertia of an object and depends on the amount of matter the object contains.
|
|
|
weight
|
The force of gravity acting on an object's mass.
|
|
|
momentum
|
The product of an object's mass and its velocity.
|
|
|
law of conservation of momentum
|
If no net force acts on a system, then the total momentum of the system does not change.
|
|
|
electromagnetic force
|
A force associated with charged particles, which has two aspects, electric force and magnetic force.
|
|
|
strong nuclear force
|
An attractive force that acts only on the neutrons and protons in the nucleus, overcoming the force of repulsion, holding them together.
|
|
|
weak nuclear force
|
An attractive force that acts only over a short range in the atom.
|
|
|
gravitational force
|
An attractive force that acts between any two masses.
|
|
|
centripetal force
|
A center-directed force that continuously changes the direction of an object to make it move in a circle.
