| Question | Answer |
|---|---|
| How do you calculate speed ? | ( distance / time ) |
| How do you calculate Average distance | ( total distance / total time ) |
| Ture or false the more momentum an object has the easy it is to stop | False |
| How can a mouse and the whale have the same momentum | if the mouse is going fast and the whale is going slow they can have the same momentum. |
| Acceleration occurs when there is a change when | velocity and direction |
| When the velocity or object changes it is being acted by | force |
| If the net force of the object is equals to zero than the object has | balanced forces |
| Which type of force of posses motion between two surfaces that are are in contact with each other | Friction |
| A tug of war that results in one team pulling the other team across the mend line is an example of | unbalanced force |
| This force is taught by gravity pulling on an object | weight |
| When the mass of the object decreases what happens to interia | increases |
| The force of gravity between the earth and the sun | 3rd law |
| Hitting a tennis ball to make it go further | 2nd law |
| Baseball hits the ground after it's thrown in the air | 1st law |
| The reason for wearing a seat belt in a moving car - | 3rd law |
| The reason for wearing a seat belt in a moving car - | 1st law |
| The reason for wearing a seat belt in a moving car | 2nd law |
| How to find average velocity | (total distance/total time ) |
| How to calculate momentum | Mass x velocity |
| How to calculate Force | mass x acceleration |
| This term means a push or a pull | force |
| True or false an object can be accelerating in it's traveling in a constant speed | true |
| Ture or false if a car is slowing down it is still accelerating | true |
| We did a lab where we used different number of rubber bands to increase the acceleration of the plastic car along the track how did the rubber bands increase the acceleration | added more force |
| When we played with straw rockets we pulled down on the rubber bands and the rockets when flying in the air which law physics were we dimentrating | 3rd law |
| Suppose a bullet is fired eastwards form the gun into a stationary wood block if the total momentum is for the ______according to the law of momentum what the law | 25 |
| True or false a object that is injected to balanced forces is moving | false |
