This experiment uses a ballistic pendulum to determine the launch velocity of a metal ball. This is compared to a measurement of the launch velocity found using projectile motion. You may wish to emphasize why energy is not conserved in the initial impact of the ball into the ballistic pendulum, but momentum is, and conversely why energy is conserved as the pendulum rises but momentum is not conserved.

See how to calculate velocity from a distance time graph, how to calculate acceleration from a velocity time graph and how to calculate distance covered from a velocity time graph! From Ramanujan to calculus co-creator Gottfried Leibniz, many of the world's best and brightest mathematical minds have belonged to autodidacts. And, thanks to the Internet, it's easier than ever to follow in their footsteps (or just finish your homework or study for that next big test).

In this video the author explains the various concepts like speed, velocity, free fall speed etc., Speed tells you how fast you are going, i.e. it is distance divided by time taken to travel it. Velocity is nothing but speed along with direction. Now she tells that acceleration is used to measure the rate of change in velocity. So she says that acceleration is difference in velocity divided by the time. She also explains that there can be acceleration with out change is speed as there can be ...

This video teaches how to use calculus find the position, velocity and acceleration of an object. Imagine an object moving on a straight line. It's position at any time (t) is given as s(t) pronounced "s of t". It's velocity is v(t)= s'(t) which is the derivative of s(t). It's acceleration a(t) is the derivative of its velocity v'(t). If we look at it from a different perspective we are differentiating. The derivative of the position is its velocity, the derivative of its velocity is it accel...

This is a great instructional video on how to calculate the age of Universe from Hubble's constant. The speed the galaxy moves away from us is directly proportional to the distance from us. Now think of big bang theory. Hubble's constant is equal to velocity over distance. 1 over Hubble's constant is equal to distance over velocity that is equal to time. Time equals to 1over 71. If you change it into all the same units words it is one over 71000 or 3.09x 10 to the power of 22. It is 3.09x10 t...

Kyle Hutchens with Live Strong demonstrates how to throw a good curveball. First grip the baseball on the side where the skinny seams come together. Take a normal pitching stance with one leg back, come through, bend your front leg and snap your wrist down through the ball to release it. Snapping your wrist down through the baseball creates the speed and the drop of the curveball. It creates less velocity than a fastball. Create the drop when your arm is between the 12 o'clock and 6 o'clock p...
