 | Term | Definition |
| |
Acceleration |
the rate at which velocity changes |
| |
Agent |
a natural force or object producing or used for obtaining specific results |
| |
Archimedes' Principle |
the rule that the buoyant force on an object is equal to the weight of fluid the object displaces |
| |
Balanced Force |
upward force exerted by a fluid on a submerged object |
| |
Center of gravity |
the point in an objet where the force of gravity appears to act |
| |
Centripetal force |
force that causes an object to lean/push against something to move in a circle |
| |
Chemical energy |
the potential energy stored in chemical bonds |
| |
Electrical energy |
the energy of electrical charges |
| |
Force |
a push or pull exerted on an object |
| |
Free fall |
the motion of a falling object when the only force acting on it is gravity. |
| |
Friction |
the force that one surface exerts on another when the two surfaces rub against each other |
| |
Gravity |
the force that pulls objects toward each other |
| |
Inertia |
the tendency of an object to resist any change in its motion |
| |
Kinetic energy |
Energy that an object has due to its motion. |
| |
Law of Conservation of Energy |
rule states that energy can't be created or destroyed |
| |
Mass |
the amount of matter in an object |
| |
Mechanical energy |
the form of an energy associated with the position and motion of an object |
| |
Momentum |
a characteristic of a moving object that is related to the mass and velocity of an object |
| |
Net Force |
the overall force of an object when all the individual forces acting on it are added |
| |
Newton's 1st Law |
an object in motion will stay in constant motion, unless it's acted upon by an unbalanced force (e.g. friction, air resistance) |
| |
Newton's 2nd Law |
acceleration depends on the object's mass and on the objects mass and on the net force acting on the object |
| |
Newton's 3rd Law |
for every action there's an equal and opposite reaction |
| |
Potential energy |
stored energy which results from the position or shape of an object |
| |
Power |
the rate at which work is done |
| |
Projectile |
an object that is thrown |
| |
Receiver |
device that detects electromagnetic waves. |
| |
Speed |
the distance an object travels per unit of time |
| |
Thermal energy |
total potential and kinetic energy of the particles in an object |
| |
Unbalanced forces |
forces that produce a nonzero net force which changes an object's motion |
| |
Velocity |
speed in a given direction |
| |
Weight |
gravity's force on an object |
| |
Work |
force exerted on an object that causes it to move |
