12.4 The 28 ft flagpole outside Martin Luther King, Jr. Elementary School casts a 42 ft shadow. In degrees, at what angle above ...
2.0 - Introduction Objects move: Balls bounce, cars speed, and spaceships accelerate. We are so familiar with the concept of mot ...
2.1 - Position Position: The location of an object; in physics, typically specified with graph coordinates. Position tells you l ...
part of this chapter, with the thought that this may prove helpful if you are familiarizing yourself with the metric system.) So ...
two hours elapse as it moves that distance. The car’s average velocity equals +50 miles divided by two hours, or +25 mi/h (+40 k ...
ǻx = displacement ǻt = elapsed time A plane flies Acme to Bend in 2.0 hrs, then straight back to Cote in 1.0 hr. What is its ave ...
we mentioned earlier, and let’s say you wanted to determine its instantaneous velocity at the midpoint of the window. You could ...
the mouse is moving from right to left. The negative displacement over a short time interval confirms that its velocity is negat ...
2.7 - Interactive problem: draw a position-time graph In this section, you are challenged to match a pre-drawn position-time gra ...
from negative to positive, yet it is accelerating at this moment since its velocity is changing. ǻv = change in instantaneous ve ...
ǻv = change in instantaneous velocity ǻt = elapsed time What is the mouse’s average acceleration? 2.10 - Instantaneous accelerat ...
Instantaneous acceleration Slope of line tangent to point on velocity-time graph The graph shows the mouse's velocity versus tim ...
Variables Part 1: Constant velocity Part 2: Constant acceleration What is the strategy? Use the definition of velocity to find ...
2.12 - Interactive checkpoint: subway train A subway train accelerates along a straight track at a constant 1.90 m/s^2. How long ...
Strategy First, we will discuss our strategy for this derivation. That is, we will describe our overall plan of attack. These st ...
We have now developed two equations that involve time multiplied by a sum of velocities. The left side of the equation in step 1 ...
