Energy
ここでカードを閲覧するか、 sign up to study with spaced repetition.
What is the Law of Conservation of Energy?
Energy cannot be created or destroyed, only transformed.
ここでカードを閲覧するか、 sign up to study with spaced repetition.
How is force defined in physics?
A push or pull that can change the motion or shape of an object.
ここでカードを閲覧するか、 sign up to study with spaced repetition.
What is the formula for force?
\(F = m \times a\)

What are the three types of motion described?
ここでカードを閲覧するか、 sign up to study with spaced repetition.
What is inertia?
The tendency of an object to resist changes in its state of motion.
ここでカードを閲覧するか、 sign up to study with spaced repetition.
What is the relationship between mass and inertia?
Greater mass results in greater inertia.

What is the physical definition of work?
The transfer of energy that occurs when a force causes displacement in the direction of the force.

What is the formula for calculating work?
\(W = F \times d \times \cos(\theta)\)
ここでカードを閲覧するか、 sign up to study with spaced repetition.
What is the physical condition required for work to be done?
Work is only done if there is movement.

How is power defined in physics?
Power is the rate at which work is done or energy is transferred.
ここでカードを閲覧するか、 sign up to study with spaced repetition.
What is the formula for calculating power?
\(P = W / t\)

How is efficiency defined?
Efficiency is the ability of a system to convert input energy into useful output.
ここでカードを閲覧するか、 sign up to study with spaced repetition.
What is the formula for efficiency?
\(\text{Efficiency} = (\text{Useful Output} / \text{Input}) \times 100\%\)
ここでカードを閲覧するか、 sign up to study with spaced repetition.
Why is no system 100% efficient?
No system is 100% efficient due to energy loss.
