Vocab
The location of an object in relation to a nearby object or place.
What is position?
The tendency of objects to resist a change in motion. An object at rest tends to stay at rest and an object in motion tends to stay in motion.
What is inertia?
A forceful impact when energy is transferred from one object to another.
What is a collision?
An object in motion will stay in motion and an object at rest will stay at rest, unless an unbalanced force acts upon it.
What is Newton's 1st Law of Motion?
The course along which something moves.
What is direction?
Any push or pull that causes an object to move, stop, change speed, change direction.
What is force?
A force that acts directly against the direction of motion. Slows things down or makes them stop.
What is friction?
Forces on an object that do not change the motion of the object.
What are Balanced Forces?
An object's acceleration depends on two factors.
What are the amount of force applied to the object AND the object's mass.
The energy of motion.
What is kinetic energy?
Desribes how fast an object is moving. How the position of an object changes during a certain amount of time.
What is speed?
A force that pulls objects down to earth. A force of attraction between two objects. The size of this force increases as the object's mass increases.
What is gravity?
The sum of all the forces acting on an object. This could balanced (causing it to stay still) or unbalanced (causing it to move).
What is net force?
Example of which of Newton's laws: You would need more force to move a car than you would a roller-skate because the car has more mass.
What is Newton's 2nd Law of Motion.
The slowing or stopping effect that one material has on another material or object.
What is resistance?
A change in position.
What is motion?
Using force to move something forward or away from the source of the force.
What is push?
All energy, stored and kinetic, within a specific system.
No change in motion can act without an unbalanced force.
What is Newtons 1st Law of Motion?
Energy of an object has because of its position of condition. "Stored energy".
What is potential energy?
The amount of matter in an object.
What is mass?
Using force to move something backward or toward the source of the force.
What is pull?
Forces on an object that cause change in the motion of the object.
What are Unbalanced Forces?
Each action has an equal and opposite reaction. Whenever an object applies force to a second object, the second object applies an equal and opposite force against the first object. FORCES always act in PAIRS.
What is Newton's 3rd Law of Motion?
The ability to do work or cause change.
What is energy?
