Vocab Flashcards
Displacement
Distance between an objects initial,or starting,position and it final position.
Acceleration
To cause to move faster.
Distance
Total length of an objects path.
Motion
Process of changing position.
Reference point
Starting point used to describe the motion or the or the position of an object.
Satellite
An object in orbit around another object.
Speed
Distance an object move divided by the time it took to move that distance.
Velocity
Speed and direction of an objects motion.
Balanced forces
Forces that act on an object,resulting in a net force of 0 N.
Combine
To unite, to join together.
Contact force
Push or pull on one object by another object by another object that is touching it.
Force
Push or pull that one object exerts on another.
Friction
Contact force that resists the sliding motion between two objects that are touching.
Gravity
Noncontact attractive force that exists between all objects
Non contact force
Push or pull on an object without touching it.
Unbalanced forces
Forces that act on an object,resulting in an net force that is not 0 N.
Accelerate
Chang in velocity.
Force pair
Two forces that result from 2 objects exerting forces on each other.
Inertia
Tendency of an object to resist a change in motion.
Newton’s first law of motion
States that if the net force of an object is zero,the motion of an object does not change.
Newton’s second law of motion
States that the acceleration of an object is equal to the net force exerted on the objects divided by the objects mass.
Newtons third law of motion
States that when one object exerts a force on a second object,the second object exerts a force of the same size,but the opposite direction,on the first object.
