Speed and velocity (motion)
Velocity
Speed is the time rate at which an object is moving along a path.
Speed
velocity is the rate and direction of an object’s movement.
Average speed is calculated by using total time and total distance:
Units
m/s
km/h
miles/h
Ecosystem
Food chain
Producer
Consumer
Apex predator
Predator/pray
Decompose
Food web
Made up with multiple food chain
Pyramid of numbers
The numbers of the organism

Gravitational
Weight
Push
Thrust
Pull
Tension
Newtons law
1st Law: Force is needed to change an object's velocity
2nd Law: F = ma
3rd Law: Every action has an equal and opposite reaction
Distance and displacement (motion)
Distance
Distance is a scalar quantity, the total distance traveled by an object;
Displacement
displacement is a vector quantity, the shortest path in a straight line between the starting position and final position.
Steps to do a experiment
Find the variables
Independent
Dependent
3<Control
Write the hypothesis
Write down the steps and the apparatus you need to use
Write down what are the risk and how to avoid it
Do the experiment more than three times to get a average
Draw a data graph and find the line of best fit
Find out if this is proportional or inversely proportional
Write a conclusion
