Kinematics

Question 1

Explain Newtons first law of motion

Answer 1

An object in motion will remain in the motion unless acted upon by an outside force

Question 2

Explain Newtons second law of motion

Answer 2

Force = mass x acceleration

Question 3

Explain Newtons third law of motion

Answer 3

For every action there is an opposite and equal reaction

Question 4

What is the conservation of energy law?

Answer 4

Energy cannot be created or destroyed. I can only change form energy can take mechanical, thermal, electrical, chemical, and nuclear forms.

Question 5

What is kinetic energy?

Answer 5

Energy that objects possess due to their motion.
KE = 1/2mv^2
M = mass (kg)
V = velocity (m/s)
KE = kinky energy (J)

Question 6

Explain potential energy vs. kinetic energy

Answer 6

Stored vs. motion

Everything has energy until the energy is enough to create a reaction where it then turns into kinetic energy.

Question 7

What is the international measurement of kinetic energy?

Answer 7

Joules

Question 8

What is kinematics?

Answer 8

The process of predicting injury patterns

Question 9

What should be considered when evaluating a trauma patients?

Answer 9

• MOI
• Force of energy applied
• Anatomy
• Energy (e.g. mass, velocity, distance, and thermal, electrical, and chemical forms)

Question 10

How is the extent of an injury defined?

Answer 10

• The type and amount of energy applied
• The speed with which energy is applied
• The part of the body to which energy is applied
