Question | Answer |
What is the formula to calculate speed? | distance travelled ____________ time taken |
What is the unit for measuring speed? | m/s |
What is it called when something or someone is moving at the same speed (a steady speed)? | Going at a constant speed. |
What does accelerate mean? | Speed up |
On a graph, if the line is flat, what does it mean? | It means that something or someone has stopped moving. |
On a graph, if the line is going upwards increasingly steeply, what is it called? | Accelerating. |
If a car is going over the speed limit, then sees a speed camera in view, what might he/she do? | The biker would've slowed down. On a graph it'd look something like a line going up steeply and then curving down a bit as the speed camera comes into view. |
What are independent variables? | Ones we can change |
What are dependant variables? | A variable whose value depends on another. |
What is correlation? | Correlation is a statistical measure that indicates the extent to which two or more variables fluctuate together. |
If the independent variable is discrete, what chart should you use? | Bar chart |
Two cars are going opposite directions, one at 70mph, the other at 60mp. How fast does it look? | 130mph because you add them together |
Two cars are going the same direction, one at 60mph, the other at 20mph. How fast does it look? | 40mph because you minus the numbers. |
What forces act on a plane in the sky? | Air resistance, Gravity, Lift and Thrust |
What does it mean when all the forces are in balance? | It means that each force is perfectly balanced by an equal force in the opposite direction. |
What is a gravitational field? | A gravitational field is an area in which an object feels a force. |
What is weight measured in? | Newton's (N) |
What is mass measured in? | Kilograms (kg) |
The force of gravity on you depends on your distance from a planet. The further away you are from the Earth, the weaker the gravitational field strength, so the weaker the force pulling you back.

What is gravity? | Gravity is the force keeping us to the ground on earth. |
