| How many feet is 1 fathom? | 6 |
| How many miles are in 1 league? | 3 |
| How many feet are in 1 mile? | 5280 |
| How many fathoms are in 20,000 leagues? | 5.28 x 10^7 fathoms |
| What is a vector? | A quantity that has magnitude and direction. |
| What is a scaler? | A quantity that only has magnitude. |
| What are the 6 vectors? | Acceleration, velocity, displacement, force, weight, momentum. |
| What are the 10 scalers? | Area, power, pressure, speed, distance, temperature, time, energy, volume, mass. |
| What is distance? | How far an object has moved. |
| What is displacement? | How far and in what direction an object has moved from its starting point. |
| What directions would lead to positive displacement? | North and east |
| What directions would lead to negative displacement? | South and west |
| What is the distance and displacement of a runner who travels 5km east then turns around and goes 3 km west? | Distance: 8km Displacement: 2km [E] or +2km |
| What is speed? | How fast an object moves |
| What is velocity? | How fast and in what direction an object has moved from its starting point |
| How is speed found? | Speed is determined by the distance covered in a certain amount of time. |
| What is the formula for determining speed? | speed = distance/time |
| In the winter olympics, American Haley Anderson won a silver medal in the open water event by swimming 10km in 1 hour, 57 minutes and 38.6 seconds. Find her speed in meters per second. | 1.42 m/sec |
| Explain the variables in the formula V=d/t when trying to find average velocity | V= average velocity (there is supposed to be a line over 'V') d= displacement t= time |
| Explain the variables in the formula v=d/t when trying to find average speed | v= average speed (there is supposed to be a line over 'v') d= distance t= time |
| What are the three ways to accelerate? | 1. An object speeds up 2. An object slows down 3. An object changes direction |
| What is acceleration? | The rate of change of velocity |
| What is the slope of a displacement time graph when direction is necessary? | Velocity |
| What is the slope of a displacement time graph when no direction is necessary? | Speed |
| What is the formula for acceleration with a velocity graph? | a=change in velocity / time a= Vf - Vi / t |
| What is normally the unit for acceleration? | m/s/s |
| What is the formula for Vf? | Vf=Vi+at |
| What is the formula for d? | d=(Vi)(t)+(1/2)(a)(t)^2 |
| What is the formula used when the data present is Vf, Vi, a and d? | Vf^2= Vi^2+2(a)(d) |
| What is the acceleration of an object moving upward with no air resistance? | -9.8 m/s^2 |
| What is the acceleration of an object free falling with no air resistance? | 9.8 m/s^2 |
