MCAT Physics Equations

PremedHQ Science Academy

Welcome to the Physics Section of PreMed HQ's MCAT Prep Course

My name is Dave Carlson and I'll be your instructor for this section. In this introduction, we will go through the core physics formulas that you need to know for the MCAT. Instead of just memorizing these formulas, I have created a flow chart to help you understand how they relate to each other and to the major SI units that we will be using. This flow chart will also help us analyze common graphs in the physics section of the MCAT.

Flow Chart of Core Physics Formulas

X (or position) - Distance or change in position over time gives you velocity

Velocity - Change in velocity over time gives you acceleration

Acceleration - Fundamental qualities in physics

Momentum - Mass times velocity

Force - F = ma

Work - Force times distance

Power - Change in work over time or force times velocity

Impulse - Change in momentum or force times difference in time

These formulas are relevant for the MCAT. Understanding impulse is important when dealing with padding or nets that lengthen the time of a collision. Power is also important as it relates to mechanics, kinematics, and electricity. It can be described as the change in energy over time.

Unit Strategy

Using units can be helpful in solving physics problems. It provides clues on how to approach the problem and can help you remember the formulas. Here is a chart that shows the units for each quantity:

Unit Chart

By understanding the units, you can easily derive the major units used in mechanics problems.

Impulse and Momentum Formulas

Impulse formulas can be memorized by associating them with the phrase "I am fat":

Impulse - Delta M or F Delta T

Momentum - Mass times velocity

Remembering these formulas will help you in the MCAT

Write The Commercial Law

ChatGPT

Commercial law, also known as business law or trade law, is a branch of civil law that governs business and commercial transactions. It encompasses a wide range of legal rules and regulations that businesses and individuals must follow when engaging in commercial activities. Some key aspects of commercial law include:

Contracts: Commercial law governs the formation, enforcement, and interpretation of contracts. It outlines the rules for creating legally binding agreements, as well as the remedies available in case of contract disputes.

Business Entities: It defines the various forms of business entities, such as corporations, partnerships, and sole proprietorships. Commercial law establishes the legal requirements and responsibilities associated with each type of business structure.

Sales and Marketing: Commercial law addresses issues related to the sale of goods and services, including product warranties, advertising regulations, and consumer protection laws.

Intellectual Property: It covers the protection of intellectual property rights, including patents, trademarks, copyrights, and trade secrets. This area of law safeguards the creations and innovations of businesses and individuals.

Competition Law: Commercial law includes antitrust and competition regulations to prevent monopolies, price-fixing, and other practices that could harm fair competition in the marketplace.

Banking and Finance: It governs financial transactions, including lending, borrowing, and banking operations. Commercial law sets rules for financial institutions and consumer financial protection.

International Trade: This aspect of commercial law deals with cross-border trade and commerce, including import and export regulations, tariffs, and trade agreements.

Commercial Dispute Resolution: Commercial law provides mechanisms for resolving disputes, including litigation, arbitration, and mediation, to ensure fair and efficient resolution of business-related conflicts.

Securities and Capital Markets: It regulates the issuance and trading of securities, such as stocks and bonds, to protect investors and maintain the integrity of financial markets.

Employment Law: Commercial law governs the employer-employee relationship, including employment contracts, labor laws, and workplace regulations.

These are some of the fundamental aspects of commercial law, but it is a broad and complex field that varies from one jurisdiction to another. Businesses and individuals involved in commercial activities should seek legal counsel to navigate the specific laws and regulations applicable to their circumstances.

A simple Zener diode shunt voltage regulator is to supply 12 V to a load which normally draws a load current which varies from 0 to 50 mA. The input voltage varies between 15 V and 18 V.

1.1 Calculate the maximum rated current value of a Zener device to be used.

1.2 Calculate the minimum power for the Zener that could be used safely.

1.3 If a 5 W rated Zener were to be used, calculate the range of possible RS. values and hence suggest a suitable standard E12 resistor value.

1.4 State four (4) conditions under which a Zener diode dissipates minimum power in a regulator circuit.

A vehicle is travelling at 72 km/h (20 m/s) when the driver sees a couple walk out on to the road 20m ahead (d=20m). The driver brakes immediately and stops just in time to avoid impact (i.e braking distance is 20m). The vehicle decelerates at a constant, gradual rate without skidding.

If the mass of the car is 1000kg, what was the work and power required to decelerate the vehicle?

An 11.0-W energy-efficient fluorescent lightbulb is designed to produce the same illumination as a conventional 40.0-W incandescent lightbulb. Assuming a cost of $0.108/kWh for energy from the electric company, how much money does the user of the energy-efficient bulb save during 110 h of use? (Give your answer to the nearest cent.)

An energy efficient lightbulb, taking in 28.0 W of power, can produce the same level of brightness as a conventional lightbulb operating at power 100 W.
