E-2 Flashcard

Front

What is chemical potential energy?

Back

Chemical potential energy is the energy stored in the bonds of chemical compounds, like atoms and molecules. It is released or absorbed during a chemical reaction.

Front

What is kinetic energy?

Back

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

Front

What is the relationship between potential energy and kinetic energy?

Back

Potential energy can be converted into kinetic energy and vice versa. For example, when an object falls, its potential energy decreases while its kinetic energy increases.

Front

What does a velocity-time graph represent?

Back

A velocity-time graph shows how the velocity of an object changes over time. The slope of the graph indicates acceleration.

Front

What is energy transfer?

Back

Energy transfer is the process of energy moving from one system or object to another, such as when a moving cart collides with a stationary cart.

Front

What is the law of conservation of energy?

Back

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

Front

What is the difference between elastic potential energy and chemical potential energy?

Back

Elastic potential energy is stored in objects that can be stretched or compressed, like springs, while chemical potential energy is stored in chemical bonds.

Front

How can you determine the interval of maximum kinetic energy increase on a graph?

Back

To determine the interval of maximum kinetic energy increase, look for the steepest slope on a velocity-time graph, indicating the greatest acceleration.

Front

What happens to energy during a collision?

Back

During a collision, energy is transferred between objects. Some energy may be converted to sound or heat, but the total energy remains constant.

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.
