Energy Transformations
Energy changing from one form into another is called this.
What is energy transformations?
Balanced forces have this net force.
What is 0?
A box is pushed with 10 N to the right and 10 N to the left. The net force is this.
What is 0 N?
Energy of motion is called this.
What is kinetic energy?
Energy cannot be created or destroyed. This scientific law explains that idea.
What is the Law of Conservation of Energy?
A toaster changes electrical energy into this main form of energy.
What is thermal energy?
If an object speeds up, slows down, or changes direction, the forces are this type.
What are unbalanced forces?
A cart is pushed with 15 N right and 5 N left. The net force is this.
What is 10 N to the right?
Stored energy due to position or arrangement is called this.
What is potential energy?
A toaster changing electrical energy into heat is an example of this.
What is an energy transformation?
Plants transform light energy into this type of energy during photosynthesis.
What is chemical energy?
An object moving at constant speed in the same direction has these types of forces acting on it.
What are balanced forces?
The unit used to measure force is this.
What is a Newton (N)?
This type of potential energy depends on height and mass.
What is gravitational potential energy?
Waves transfer this, but not matter.
What is energy?
During energy transformations, some energy is usually transferred to surroundings as this.
What is heat or thermal energy?
The sum of all forces acting on an object is called this.
What is net force?
According to Newton’s Third Law, every action has this.
What is an equal and opposite reaction?
Food, batteries, and fossil fuels contain this type of potential energy.
What is chemical potential energy?
In a transverse wave, particles move in this direction compared to the energy.
What is perpendicular?
Where on a roller coaster is the potential energy the greatest? The lowest?
What is the top, and what is the bottom?
A heavy shopping cart and an empty shopping cart are pushed with the same force. Which one will be harder to move and why?
What is: The heavy cart because greater mass resists changes in motion more? (greater inertia?)
When a swimmer pushes water backward, the water pushes the swimmer forward. This is an example of which law?
What is Newton's Third Law?
A stretched rubber band stores energy because of its shape and position. This energy is called what?
What is elastic potential energy?
In a sound wave, the particles move back and forth in the same direction as the wave energy. This type of wave is called what?
What is a longitudinal wave?
