| Question | Answer |
|---|---|
| Newton's first law of motion | An object at rest stays at rest and an object at motion stays at motion until acted on by a net force |
| Newton's second law of motion | F=MA |
| Newton's third law of motion | For ever action (force), there is an equal but opposite reaction |
| the tendency of an object to resist a change in motion... unless an outside force acts upon it | inertia |
| a measure of the gravitational force exerted on an object | weight |
| the motion of a body when only the fore of gravity is acting on the body | free fall |
| the constant velocity of a free falling object when the force of air resistance in equal in magnitude and opposite in direction to force of gravity | terminal velocity |
| the curved path that an object follows when thrown, launched. or otherwise projeted near the surface of the earth | projectile motion |
| a quality defined as the product of the mass and velocity of an object | momentum |
| What is one newton equal to? | 1kg x m/s^2 |
| What is momentum equal to? | 1kg x m/s |
| what are weight and force measured in? | newtons |
| what is measured in newtons? | weight and force |
| What are the four concepts? | weight influences shape............ All matter is effected by gravity......... g increases as m increases ........... g decreases as d increases |
| Formula for momentum | p=mv |
| formula for force | f=ma |
| formula for weight | w=mg |
| invert p=mv to find mass | m=p/v |
| invert p=mv to find velocity | v=p/m |
| invert f=ma to find mass | m=f/a |
| invert f=ma to find acceleration | a=f/m |
| invert w=mg to find mass | m=w/g |
| invert w=mg to find gravity | g=w/m |
