## How do you calculate velocity in AP Physics?

Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.

#### Is AP Physics 1 or C harder?

Data table: AP classes ranked by difficulty hardest to easiest

AP CLASS Our OVERALL ASSESSMENT EASY TO SELF STUDY? (10=Hardest)
Physics 1 Very Hard 7.5
Chemistry Very Hard – and hardest to self-study 8.4
Physics C – Mechanics Very Hard – but high pass rate 6.6
English Literature Very Hard – and low pass rate 7.0

Is AP Physics harder than AP Physics?

Algebra based physics isn’t necessarily easier than calculus based physics, however, the AP Physics C: E/M class is generally regarded as a harder class than AP Physics 1. The class covers almost twice the amount of material (E&M and mechanics) and is thus faster paced than AP Physics 1.

What is the equation to find velocity?

To figure out velocity, you divide the distance by the time it takes to travel that same distance, then you add your direction to it. For example, if you traveled 50 miles in 1 hour going west, then your velocity would be 50 miles/1 hour westwards, or 50 mph westwards.

## How do you find velocity in a lab?

The simplest way to measure velocity is to use a stop watch and a meter stick. Unless one is careless, human error can seldom be attributed to errors in experiments. However a stop watch is only as good as the human controlling it.

### Which AP Physics is the easiest?

AP Physics 1 Physics 1 has the lowest pass rate of any AP exam (42.1%) along with one of the lowest percentages of students scoring a 5 (just 6.9%). Physics 1 is an algebra-based physics class that explores topics such as Newtonian mechanics, simple circuits, and mechanical waves.

#### What is the formula to find final velocity?

Final velocity (v) of an object equals initial velocity (u) of that object plus acceleration (a) of the object times the elapsed time (t) from u to v. Use standard gravity, a = 9.80665 m/s2, for equations involving the Earth’s gravitational force as the acceleration rate of an object.
