| An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in same dirction unless acted upon by an unbalanced force | Newton's First Law |
| The resistance of any physical object to any change in its state of motion. Its tendency is to keep objects moving in a straight line at a constant velocity | inertia |
| It retains its state of rest or its velocity along a straight line. So as long as it in not acted upon by an external force | property of matter |
| The law of inertia | Newton's First Law |
| a push or pull | force |
| Resists a change in motion | Inertia |
| scientific unit for force | Newton (N) |
| force that acts between two objects to resit motion (acts opposite of the way they want) | friction |
| force of gravity; measured in newtons | weight |
| A force of attraction between objects that is due to their masses. | gravity |
| he acceleration of an object depends on the mass of the object and the amount of force applied. | Newton's 2nd Law |
| For every action there is an equal and opposite reaction | Newton's 34d Law |
| The _____________ mass an object has the stronger the gravitational force. | more |
| The ______________ two objects are the stronger the gravitational force. | closer |
| action - reaction | Newton's 3rd Law |
| F = m x a | Newton's 2nd Law |
| The unbalanced force required to accelerate a 2.0 kg mass at 4.0 m/s2is | 8.00 N |
| An object accelerates 3.0 m/s2 when a force of 6.0 newtons is applied to it. What is the mass of the object? | 2.00 kg |
| An object with a mass of 2.0 kg has a force of 4.0 newtons applied to it. What is the resulting acceleration of the object? | 2.00 m/s^2 |
| When you sit in your chair, your body exerts a downward force on the chair and the chair exerts an upward force on your body. | 3rd Law |
| rolling, sliding, fluid, static | types of friction |
| more mass, more force | Newton's 2nd Law |
| A person not wearing a seat belt flies through a car window when someone slams on the brakes because the person's body wants to remain in continuous motion even when the car stops. | Newton's 1st Law |
| Rockets are launched into space using jet propulsion where exhaust accelerates out from the rocket and it accelerates in the opposite direction. | Newton's 3rd Law |
| When riding a horse , the horse suddenly stops and you fly over its head. | Newton's 1st Law |
| A soccer ball accelerates more than a bowling ball when throw | Newton's 2nd Law |
| Firing a gun | Newton's 3rd Law |
| reaching maximum velocity | terminal velocity |
| refers to motion in a curved path representing accelerated motion, and requires a force directed toward the center of curvature of the path. This force is called the centripetal force which means "center seeking" force. | centripetal force |
| Also known as terminal speed | terminal velocity |
| air resistence | Drag |
| upward acting force on a wing or airfoil | lift |
| states that an increase in the speed of moving air or a flowing fluid is accompanied by a decrease in the air or fluid's pressure. | Bernoulli’s Principle |
| refers to forces that oppose the relative motion of an object through a fluid such as a liquid or gas. | drag |
| is used to overcome the drag of an airplane, and to overcome the weight of a rocket | thrust |
| P before = P after | law of conservation of momentum |
| F x t | formula for impulse |
| momentum can't be created or destroyed, only transferred | law of conservation of momentum |
| amount of force applied during an interval of time | impulse |
| N s | scientific units for impulse |
