work and energy

Front

What is the formula for calculating work done?

Back

Work (W) is calculated using the formula W = F × d, where F is the force applied and d is the distance moved in the direction of the force.

Front

What unit is work measured in?

Back

Work is measured in Joules (J).

Front

How is kinetic energy defined?

Back

Kinetic energy is the energy an object possesses due to its motion, calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

Where is potential energy highest in a pendulum?

Back

Potential energy is highest at the highest points of the swing.

Front

What is the relationship between work and energy?

Back

Work is a transfer of energy; when work is done on an object, energy is transferred to that object.

Front

What is the definition of energy?

Back

Energy is the ability to do work or cause change.

Front

How do you calculate the distance moved if work and force are known?

Back

Distance can be calculated using the formula d = W / F, where W is work done and F is the force applied.

Front

What is the principle of conservation of energy?

Back

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

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, calculated using the formula PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

How does increasing the force affect the work done?

Back

Increasing the force applied to an object increases the work done, assuming the distance remains constant.
