Work and Energy Flashcard

Front

What is the correct unit for energy?

Back

Joules (J)

Front

As a pendulum swings from its highest to lowest position, what happens to its kinetic and potential energy?

Back

The potential energy (PE) decreases while the kinetic energy (KE) increases.

Front

What happens to the kinetic energy as the ball falls from point A to point C?

Back

It increases.

Front

Energy due to motion is ____________ energy.

Back

Kinetic energy.

Front

If the 1.2 kg basketball rolls at 3 m/s, what is its kinetic energy?

Back

5.4 J.

Front

What is the formula for calculating kinetic energy?

Back

KE = 0.5 * m * v^2, where m is mass and v is velocity.

Front

What is potential energy?

Back

Energy stored due to an object's position or configuration.

Front

What is the formula for gravitational potential energy?

Back

PE = m * g * h, where m is mass, g is acceleration due to gravity, and h is height.

Front

How does energy conservation apply to a pendulum?

Back

The total mechanical energy (PE + KE) remains constant if no external forces act on it.

Front

What is the relationship between work and energy?

Back

Work done on an object results in a change in its energy.
