- Define mass. Define inertia
- Mass: the quantitative measure or an objects inertia
- Inertia: the tendency of an object to remain in its present state of motion
What are the four forces in nature
- Strong and weak nuclear forces
- Electromagnetic
- Gravity
Define Newtons laws
- 1: law of inertia. Objects request changes in motion
- 2: F=ma which means change in motion/acc is inversely proportional to the size of the object and the force required to change the motion is directly proportional to the size of the object
- 3. Equal and opposite reaction, the opposite reaction never occurs in the reaction system
Give the equationa for centripetal acceleration and centripetal force
- Ac= (V^2)/r
- Fc=mAc
What is the equation for force exerted by friction. What are the friction types
- Ff=(friction coefficient)(normal force)
- Static and kinetic, static is stronger
Define Hooke's law
- F=-k(delta(x))
- The force exerted by a material is proportional to a constant times the amount of displacement experienced by the material by an external force
