Speed
How is speed of an object measured?
Metres per second
What is mass?
A large body of matter with no definite shape.
What is the definition of energy?
The capacity or power to do work.
What is the dependant variable?
A dependent variable is the variable being tested and measured in a scientific experiment.
What is Newton's first law?
An object will remain at rest or in uniform motion in a straight line unless acted upon by an external force (know as inertia)
What is net force?
Unbalanced force
What is weight?
The weight of an object is the force of gravity on the object.
Measured in Newton's
What are the 6 types of energy?
Kinetic energy, chemical energy, potential energy, light, heat and sound.
What is the independent variable?
An independent variable is the variable that is changed or controlled in a scientific experiment
What is Newton's second law?
The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.
Force = mass x acceleration
What is acceleration?
A change in speed.
How is Mass measured?
Kilograms or grams.
What is the law for the conservation of energy?
The Law of Conservation of Energy states that energy cannot be created or destroyed, just transformed or transferred from one form to another.
What is the controlled variable?
Controlled variables are quantities that a scientist wants to remain constant.
What is Newton's third law?
For every action, there is an equal and opposite reaction.
How is distance measured?
With a 50m measuring tape
What is force?
Strength or energy as an attribute of physical action or movement.
What is a Sankey diagram?
A diagram that shows energy distribution including wasted energy.
What is a fossil fuel?
A natural fuel such as coal or gas, formed in the geological past from the remains of living organisms.
Also know as Finite fuels as they will eventually run out.
What are Newtons?
The newton is the Standard International (SI) unit of force.
It is usually abbreviated N.
One newton is the force required to cause a mass of one kilogram to accelerate at a rate of one meter per second squared in the absence of other force-producing effects.
What is the equation for speed?
Speed= distance / time
What is the difference between Mass and Weight?
Mass is characteristic of a body (how much stuff is in something)
Weight is the force of gravity on the Mass.
Name the types of energy transformations that you undergo whilst having breakfast?
Kinetic from making
Chemical potential in the cereal
Heat from when your body metabolises the food
Name an alternative fuel and state what the advantages are over fossil fuels.
Wind, solar, electric engines.
In what year did Newton formulate his laws?
Newton developed his laws of motion in 1666, when he was only 23 years old.
