Question | Answer |
---|---|
Net Force | The overall force on an object when all individual forces acting on it are added together. |
Law of Conservation of Momentum | The rule that in the absence of outside forces the total momentum of objects that interact does not change. |
Centripetal Force | A force that causes an object to move in a circle. |
Tension | An elastic force that stretches or pulls on the molecules in matter. |
Sliding Friction | Friction that occurs when one solid surface slides over another. |
Unbalanced Force | Forces that cause an object's velocity to change. |
Air Resistance | The fluid friction experienced by objcets falling through the air. |
Rolling Friction | Friction that occurs when an object rolls over a surface. |
Gravity | The force that pulls objects toward each other. |
Newton | The SI unit used for magnitude, or strength, of a force. |
Weight | A measure of the force of gravity on an object. |
Fluid Friction | Friction that occurs when as an object moves through a fluid. |
Force | A push or pull exerted on an object. |
Static Friction | Friction that acts on objects not moving. |
Inertia | The tendency of an object to resist any change in its motion. |
Compression | An elastic force that squeezes or pushes the molecules in matter together |
Satellite | Any object that orbits around another object in space. |
Balanced Forces | Equal forces action on an object in opposite directions. |
Momentum | The product of an object's mass and velocity. |
Mass | A measure of how much matter is in an object. |
Friction | The force that one surface exerts on another when the two surfaces rub against each other. |
Free Fall | The motion of a falling object when the only force acting on it is gravity. |
Projectile | An object that is thrown. |
