equations of kinematics: v = u + at, , , v2 = u2 + 2aΔs where, u = initial velocity, v = final velocity, s = displacement/distance moved, a = acceleration, t = time components of a vector: two (or three in three dimensions) mutually perpendicular vectors that, when added together, form the vector itself—
Part 1 - Speed Calculations: Use the speed formula to calculate the answers to the following questions. Be Be sure to show your work for each problem (write the formula, numbers with correct units, and the answer with
Write down all the variables you have and the one you are asked to find, then see which equation you can use. These equations can only be used for motion with UNIFORM ACCELERATION.
Like work, power has a strictly defined meaning in physics: the rate at which work is done. In physics work is defined as: work done = force × distance moved ∆W = F∆s Two men push crates the same distance across the floor at the same steady speed. The bigger, heavier crate needs more force, because of greater frictional resistance.
