Flashcard 6 - Matter & Energy

Front

What type of friction is experienced when an object is sliding over a surface?

Back

Kinetic friction.

Front

What is the process called when energy is transferred from one object to another using a force?

Back

Work.

Front

Which of Newton's laws states that for every action, there is an equal and opposite reaction?

Back

Newton's Third Law.

Front

How do you calculate power when energy is transferred over time?

Back

Power = Energy transferred (J) / Time (s).

Front

What force keeps an object moving in a curved path?

Back

Centripetal force.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic Energy = 1/2 mv², where m is mass and v is velocity.

Front

What is the definition of work in physics?

Back

Work is done when a force causes an object to move in the direction of the force.

Front

What is the unit of power in the International System of Units (SI)?

Back

Watt (W).

Front

What is the relationship between force, mass, and acceleration according to Newton's second law?

Back

Force = Mass × Acceleration (F = ma).

Front

What is the difference between potential energy and kinetic energy?

Back

Potential energy is stored energy based on position, while kinetic energy is the energy of motion.
