5. Energy stored in the body due to an applied force

Try these first

1. 1.

   What is the formula to calculate energy stored in a spring?

   Hint

   Think about how deformation relates to the energy stored.

2. 2.

   What does the spring constant 'k' signify?

   Hint

   Higher k implies a stiffer spring.

3. 3.

   What is the formula for energy stored in a spring?

   • E = kx
   • E = (1/2)kx²
   • E = kx²

   Hint

   Consider how displacement increases energy storage.

4. 4.

   True or False: The energy stored depends on the path of force application.

   • True
   • False

   Hint

   Think about different scenarios of force application.

5. 5.

   A material experiences a tension of 50 N with a displacement of 0.2 m. Calculate the energy stored if the spring constant is 250 N/m.

   Hint

   Apply the formula for energy stored in a spring.

6. 6.

   Two forces (50 N and 25 N) are applied to a body with displacements of 0.1 m and 0.05 m, respectively. Calculate the total energy stored.

   Hint

   Remember to consider the contributions from each force.
