The total energy of a pendulum is conserved. That is the total energy T is a constant. We define the potential energy to be zero when the pendulum is hanging vertically, with an opening angle of µ˘0. The potential energy is largest when the kinetic energy is zero and opening angle is maximized i.e. at the top of the pendulum’s swing.

Kinetic energy is an energy of motion. Again, an object does not have an absolute amount of kinetic energy (K), only an amount relative to some point. The formula for K is: eq. 2 where m is still mass and v is velocity. Since motion is relative (ask Einstein) an object in …

Ballistic Pendulum 1 KW 3/20/19 Introduction: The ballistic pendulum is a pendulum with a device on the bottom end that “catches” a projectile from some type of launcher, and then converts the kinetic energy transferred to the catcher at the bottom of the swing, to gravitational potential energy as it swings up to a maximum height.

During this collision some of the energy may be dissipated as heat or sound, therefore mechanical kinetic energy is not conserved during the collision. Conservation of Energy: After the collision the pendulum/projectile combination (mass m=m 1 +m 2) has initial speed v=v (1+2). This means it has kinetic energy K= ½ mv2. We can determine how ...

The important thing to remember with the ballistic pendulum experiment is this is an inelastic collision so the kinetic energy of the pendulum after the collision and the kinetic energy of the ball are not the same. This is because kinetic energy cannot be conserved in inelastic collisions.
