# AP Physics 1: 1.1 Object Interaction and Forces

If there's one good thing about the heat death of the universe, it's that we'll all have an excellent excuse for dodging physics homework.

well a particle is at rest at x equals 5 M at time T equals 0 s the particle

begins to move with an initial velocity of 2 meters a second and maintains an [equation of movement of particles]

acceleration of 1 meter per second squared well particle moves in a

straight line in the positive x-direction what is the location of the

particle at T 1 equals 6s and here's potential answers all right [muttering potential answers]

well there are ton of numbers in this question luckily we're

OK at math otherwise we might be in trouble now in order to solve this [Boy at his desk doing math homework]

problem we need to use our equation of motion which looks a little something

like this in this equation X represents distance V represents velocity A is [physics equation for motion]

acceleration and T is time well X sub 0 is the starting distance and V sub 0 is the

starting velocity well let's do a roll call to make sure we've got [Roll Call check list on a clipboard]

everything we need Kizer well do we have a starting distance yep that's 5 meters

how about a starting velocity that's 2 meters a second acceleration you hear

well 1 meter per second squared got it and last but not least time err that'd be

six seconds pop all that into our equation and what pops out is 35 meters

so option C is the answer these equations are going to come in handy so

[Boy hitting his laptop in frustration] we better start memorizing them after all the heat death of the universe isn't

expected to occur for at least 10 to the hundredth years so we can't rely on that [Earth covered by fire]

to avoid the AP physics exam.
