physics lecture 1

The five steps to solving a physics question

This is a physical quantity that has magnitude but no direction

this has a physical quantity with both magnitude and direction. Can be represented by an arrow

A² + B² = C²

What does SOH CAH TOA stand for?

Any vector can be replaced by this type of vector. They are always at right angles to each other and their sum is equal to the vector being replaced.

The most common triangle for the MCAT

scalar: Distance/time =
vector: displacement/time=

This vector is defined as the rate of change in velocity either in magnitude or direction.
Change in velocity/time

uniformly accelerated motion is motion with constant acceleration.
What are the three uniformly accelerated motion?

what is the equation for average veolcity?

The peak height for the projectile formula

A large one of these increases air resistance because it allows for more collisions with air molecules

This is created when projectile collides with air molecules. It is a type of friction that is affected by surface area, shape, and velocity. Mass doesn't change it but it can alter the path of the projectile.

formula for speed

formula for velocity

formula for acceleration

another formula with constant acceleration
v= square root(2gh)
what is the value of g?
