When a mass [ measured in kilograms ( kg ) ] is under the influence of balanced forces, it will either sit still with respect to an observer that is also ” at rest ” within the same frame of reference ( Ex. A television set across a room from a viewer. ), or itContinue reading “AP PHYSICS: The Gravitational Constant of Acceleration”

KINEMATICS: Total Time of Flight for a Projectile
Q: A model-rocket club is standing at the edge of a 40.0 m building. They arrange a launcher so that it is off the cliff’s edge, and they launch a rocket straight upward at an initial velocity ( v ) of 380.0 m/s. Neglecting wind resistance, how long will it take for the rocket toContinue reading “KINEMATICS: Total Time of Flight for a Projectile”
