Science

In science, we have been learning about how to

calculate speed - Speed is a measure of how far an object can travel in a certain amount of time. We used the formula V(speed)= d (distance) / t (time). 

Aerodynamics - As air moves down over the rear wing of the car, it produces a downforce. This downforce helps the car maintain grip when cornering at high speeds.

Mass & Weight - The mass of an object is the amount of matter or "stuff" it contains. The more matter an object contains the Greater its mass. 

Friction - Friction is a force that occurs when two materials rub together. Friction always acts to oppose (prevent or stop) the movement of an object. Drag is another name for the friction that occurs when an object moves through a fluid, such as water.

Calculating forces - The amount of force acting on an object can be calculated using its mass and its acceleration. A scientist shows the relationship between force, mass, and acceleration using the formula:

(F net = ma)

Balanced and Unbalanced Forces - Balanced forces are forces that act on an object but cancel each other out because they are the same size and are acting in opposite directions. 

Forces, and Motion - In physics, a force is any interaction that, when unopposed, will change the motion of an object. 

Yesterday in class we used our learning to investigate Speeding Past School 

- As group we present our idea to the teacher. By investigating cars at the side of the road. Measuring Cars Speed passing school. (To convert speed measured in m s-1 o km hr-1 multiply by 3-6) 

Calculating 10 Cars and figuring it's speed by: V(speed)= d (distance) / t (time).  (Distance Devided by time)  

- Coordination improve to try and accurate, measure and time the cars.
