2.1.1. Definition and Physical Meaning

Try these first

1. 1.

   What is inertia?

   Hint

   Think about how objects behave when you push them.

2. 2.

   Write the equation relating inertia to force and acceleration.

   Hint

   Recall how mass, acceleration, and force are connected.

3. 3.

   What does inertia refer to?

   • Resistance to change in motion
   • The force of gravity
   • Speed of an object

   Hint

   Think back to Newton's First Law.

4. 4.

   True or False: Inertia increases with higher mass.

   • True
   • False

   Hint

   Consider how heavy objects behave compared to lighter ones.

5. 5.

   A structure weighing 5000 kg is subjected to an earthquake causing an acceleration of 2 m/s². Calculate the inertia force acting on the structure.

   Hint

   Apply the formula F = ma.

6. 6.

   Compare the inertia effects on a tall building versus a small structure during seismic activity. Discuss the design implications.

   Hint

   Consider how mass and height amplify inertia's effects.
