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
