Forces
| Question | Answer |
|---|---|
| What is a Force? | a push or pull exerted on an object |
| What is a Newton? | a unit of measure that equals that |
| Define Net Force? | The overall force on an object wham all the individual forces action on it are adding |
| Unbalanced forces are? | Forces that produce a nonzero net force which changes an objects motion |
| What is the SI unit for force? | Newtons |
| What is Free fall? | When the only force action on an object is gravity |
| Mass is? | a measure of the amount of matter in an object |
| Define Gravity? | the force that pulls objects together |
| Terminal Velocity is? | The greatest velocity that an object can reach |
| What type of motion is in act where a basketball is thrown in a hoop? | Projectile Motion |
| What is Friction? | The force that two surfaces exert on each other |
| What are the two factors that friction depends on? | How hard the surfaces pouch together and the type of surface it is |
| What is Static Friction? | The friction that acts on objects that are not moving |
| What is Sliding Friction? | when two solid surface slide over each other |
| What is Rolling Friction? | When an object rolls across a surface |
| What is Fluid Friction? | When a solid object moves through a fluid or gas |
| The law of universal gravitation states? | That the force of gravity acts between all objects in the universe |
| What two factors affect the gravitational attraction between objects? | Mass and distance |
| What is the definition of Weight? | The force of gravity on a person or object at the surface of a planet |
| What is 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 velocity, unless it is acted upon by an unbalanced force. |
| What is it when the tendency of an object to resist a change in motion? | Inertia |
| What is Newtons Second Law of Motion? | Acceleration depends on the objects mass and on the net force acting on the object |
| What is 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. (for every action there is an equal but opposite reaction.) |
| What is Momentum? | A characteristic of a moving object that is related to the mass and the velocity of the object |
| How can momentum be determined? | By multiplying the objects mass and velocity |
| What is the law of conservation of momentum? | the total momentum of objects that interact does not change. |
