to apply a force
What is exert?
This is required to change the velocity of an object
What is a force?
Energy in motion
What is kinetic energy?
This is kept the same in an investigation
What is a control variable?
A push or a pull that can change a motion of an object
What is a Force?
An event or process that leads to a result or change
What is a cause?
How an object changes velocity depends on this
Energy stored
This is measured and recored in a lab
What is a dependent variable?
A result or change that happens because of an event or process
What is an effect?
Speed in a particular direction
What is velocity?
A stronger force and cause this
What is a greater change in velocity?
A set of interacting parts forming a complex whole
What is a system?

What is a cause and effect relationship?
Examples of this type of energy include: wind, water and sunlight
What is renewable energy?
The IV is Force strength and the DV is the change in velocity. Write the scientific question.
How does the force strength affect the change in velocity?
A force between an object and the surface it is moving over
What is friction?
Another name for Newton's 1st Law
What is Inertia?
an object in motion will continue with constant speed and direction unless acted on by an unbalance force
What is Newton's 1st Law?
This law states nothing creates energy. If something has energy the energy must have been transferred from something else.
What is the Law of Conservation of Energy?
