Motion- Dr. Tina CISS
Terms in this set (35)
the friction that opposes the motion of falling objects and moving objects, when air hits the surface of an object.
a quantity that shows both magnitude (amount) and direction.
a push or pull exerted by one object on another.
the forces acting on an object when the net force is not zero.
forces that produce a net force equal to zero.
a measurement for force (N)
an object's change in position over time
how far an object travels
a force that works against motion, caused by tiny bumps and ridges in surfaces.
a rate of motion that depends on the distance an object travels over a period of time
a term used to describe an object's speed AND direction.
the rate at which velocity changes
the tendency of an object to resist a change in motion.
Newton's 1st Law of Motion
An object at rest tends to stay at rest and an object in motion remains in motion unless acted on by an unbalanced force.
Newton's 2nd Law of Motion
The acceleration of an object depends on the mass of the object and the force applied. A math equation that represents this law is: force = mass x acceleration (F=m x a)
Newton's 3rd Law of Motion
Every action has an equal and opposite reaction.
Location of that place or object
A location to which you compare other locations
The overall TOTAL force acting on an object when ALL forces are combined
Force that objects exert on each other because of their masses.
The force of gravity acting on an object (Scale).
an amount of something measured per unit of something else; many rates describe changes or events that happen over time
A statement that describes what scientists expect to happen every time under a particular set of conditions
when referring to forces, pulling together
The path of an object as it revolves around another object in space
a map of a force field that can be used to predict which way gravitational forces will pull an object
a model that describes what the force on an object would be if the object were placed in any location in space; usually used to predict the strength and direction of noncontact forces
A measure of the amount of matter in an object
A measure of mass in motion. The momentum of an object is the product of its mass and velocity.
A situation in which two objects in close contact exchange energy and momentum.
conservation of momentum
The total momentum of a system of objects does not change, as long as no outside forces are acting on that system.
A point of view on the speed and direction that objects are moving and what reference point they are moving relative to.
the requirements that must be met for an engineering solution to be successful.
limitations on an engineering solution.
always attractive, non-contact forces between objects that have mass.
