Researching a new medical cure… unlocking DNA’s secrets… or developing a more resilient variety of wheat… biochemists and biophysicists study living things and the processes that make them grow, change, and die. These scientists design and conduct experiments, such as testing the effects of drugs, or learning how different cells divide and grow. They may

hello this is Tom for EveryStepPhysics.com I write those programs for the TI-89 titanium and other calculators in the TI system we’re doing this problem here which is a standard problem of tension and um let’s get started. Of course we put physics in here with close parentheses open/close parenthesis so that you get to

EVERY physical variable (distance, time, mass, speed, energy, and so on) has units of measurement. For example, the agreed-upon international unit of speed (and of velocity) is the meter per second, abbreviated m over s. Sometimes international units are inconvenient. For example, if you happen to be speeding in the United States, you might need

In RP2, we got a feel for the meaning of speed and velocity. Now is the time to define these little beasties more carefully. We’ll start by doing something weird: we’ll constrain movement to one dimension: that’s motion in a straight line, either forward or backward. If we can describe 1-dimensional motion, then maybe it

Before we start this lesson, I recommend that you watch the video of the lesson in which we talked about the equation for velocity and time. In this particular lesson, we’re going to learn about the equation for position and time. Let’s start that by looking at this graph. You can see that this is
