newtons laws
Question | Answer |
---|---|
Force | Push or Pull |
Unbalanced Force | Forces that produce a nonzero net force, which changes an objects motion |
Speed | The distance an object travels per unit of time |
Momentum | The product of an objects mass and velocity |
Net Force | The overall force on an object when all the individual forces acting on it are added together |
Gravity | The force that pulls objects toward each other |
Velocity | Speed in a given direction |
Weight | The force of gravity on an object at the surface of a planet |
Friction | The force that one surface exerts on another when the two surfaces rub against each other |
Newton | A unit of measure that equals the force required to accelerate 1 kilogram of mass at 1 meter per second per second |
Balanced Force | Equal forces acting on an object in opposite directions |
Inertia | The tendency of an object to resist any change in its motion |
Motion | The state in which one object's distance from another is changing |
Potential Energy | Stored energy |
Kinetic Energy | Energy that an object has due to its motion |
Acceleration | The rate at which velocity changes |
Newtons First Law of Motion | "An object at rest will remain at rest, and an object moving at a constant velocity will continue moving at a constant velocit, unless it is acted upon by an unbalanced force." Another name is Law of Inertia |
Mass | The amount of inertia depends on this |
Newtons Second Law of Motion | "Acceleration depends on the objects mass and on the netforce acting on the object." |
Newtons Third Law of Motion | "If one object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction on the first object." |
