Kinetic and Potential Energy

Front

Energy due to motion is ____________ energy.

Back

Kinetic energy is the energy that an object possesses due to its motion.

Front

What kind of energy is in a waving hand?

Back

Kinetic energy is present in a waving hand because it is in motion.

Front

Which point has the most potential energy? (Options: G, f, b, a)

Back

Point a has the most potential energy, as it is at the highest position.

Front

A 2600 kilogram car is moving at a speed of 25 m/s. How much kinetic energy does the car have?

Back

The kinetic energy of the car is 437,500 J, calculated using the formula KE = 0.5 * m * v^2.

Front

Food has _________ energy.

Back

Food has potential energy, which is stored energy that can be converted into kinetic energy when consumed.

Front

Define potential energy.

Back

Potential energy is the energy stored in an object due to its position or state.

Front

What is the formula for calculating kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 0.5 * m * v^2, where m is mass and v is velocity.

Front

Give an example of potential energy.

Back

An example of potential energy is a rock at the top of a hill, which has energy due to its height.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is the relationship between kinetic and potential energy in a pendulum?

Back

In a pendulum, kinetic energy is highest at the lowest point, while potential energy is highest at the highest points.
