GCSE Physics Unit 2: Work and Energy

What is the measure of energy transferred when a force acts on a body?

• Energy

  Kilowatt

• Work Done

  Joule

• Effort

  Newton

• Torque

  Newton metre

Fill in the blank: Work is calculated using the equation: Work = force × ________.

• distance

• time

• velocity

• mass

Which statement explains the concept of 'total energy in the system must remain the same'

• The total energy in a system is always constant, regardless of the processes happening within it.

• Energy can be created or destroyed in a closed system.

• The total energy in a system can increase over time.

• Energy is only conserved in mechanical systems.

The spring constant formula is used to understand how a given applied force will affect the displacement a spring travels based on its spring constant, or the stiffness of the spring.

The spring constant formula is:

• F = Mx

• F = -Kx

• F = Kx

• F = Ma

What is the unit of the spring constant in the International System of Units (SI)?

• Watt (W)

• Joule (J)

• Newton per meter (N/m)

• Pascal (Pa)

Which of the following is an example of potential energy?

• Flowing water

• A compressed spring

• A moving car

• Burning fuel

Fill in the blank: Kinetic energy is calculated using the equation: Kinetic Energy = 0.5 × mass × ________.

• velocity squared

• time

• acceleration

• distance

Which of the following equations represents Hooke's Law?

• F = -kx

• F = mv

• F = ma

• F = kx

What is the potential energy of an object with mass m at height h above the ground?

• mgh

• 0.5mv^2

• Fh

• mgh^2

Which of the following is a unit of work in the International System of Units (SI)?

• Joule (J)

• Watt (W)

• Newton (N)

• Pascal (Pa)
