E-2 Flashcard

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass of the object and the square of its velocity.

Front

How does energy transfer differ from energy conversion?

Back

Energy transfer involves energy moving from one object to another, while energy conversion involves changing energy from one form to another within the same object.

Front

What are complex carbohydrates?

Back

Complex carbohydrates are made up of sugar molecules that are connected together in long, complex chains. They provide a more sustained energy release compared to simple sugars.

Front

What happens to kinetic energy as an object speeds up?

Back

As an object speeds up, its kinetic energy increases.

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the significance of energy conversions in daily life?

Back

Energy conversions are significant because they allow us to use energy in various forms, such as converting chemical energy in food to kinetic energy for movement.

Front

What is the role of sugars in energy production?

Back

Sugars are a quick source of energy for the body, providing immediate fuel for physical activities.

Front

What is the difference between potential energy and kinetic energy?

Back

Potential energy is stored energy based on an object's position or state, while kinetic energy is the energy of motion.

Front

What is an example of energy transfer?

Back

An example of energy transfer is when a ball is thrown, transferring energy from the thrower's arm to the ball.

Front

What does it mean for energy to be conserved?

Back

The conservation of energy means that energy cannot be created or destroyed, only transformed from one form to another.
