Please explain these questions for me.

1) Using the conceptsof Linear Momentum and Impulse in car crashes, how can the Forces over the occupants of the vehicle involved in a crash be decreased?

How do you apply the conservation of momentum principle in collisions?

2) Describe the three different ways to determine the torque of a given force

Define moment of Inertia

What is the relationship between angular acceleration, net torque, and moment of Inertia

3)How do youapply the two conditions for static equilibrium to solve problems?

4)Is the velocity of a simple harmonic oscillator ever zero? If so, where?

Is the acceleration of a simple harmonic oscillator ever zero? If so, where?

5) What is temperature?

Which is larger, 1 C or 1 F? Explain Why?

6)Explain the difference between Internal Energy and Heat

What is the definition of specific heat?

What is the main idea used in Calorimetry experiments?
