| Question | Answer | |
|---|---|---|
| How do you calculate time using the speed formula? | t=d/s | |
| How do you calculate distance using the speed formula? | d=st | |
| What is the difference between speed and velocity? | Speed is the measure of how fast or slow an object is going whereas velocity is a measure of the speed of an object in a particular direction. | |
| What happens when you combine velocities? | You either add or subtract them. | |
| How do you calculate the acceleration rate of an object? | endv-startv/t | |
| What is the difference between deceleration and acceleration? | Deceleration is decreasing your speed whereas acceleration is increasing your speed. | |
| What is G-force? | The amount of pressure that's produced when a roller coaster car changes direction. | |
| How do you calculate G-force? | g-force=speed (ft/sec)2/32.2xradius(in feet) | |
| How do you calculate the speed/velocity of an object? | s=d/t |
