5.1 Speed, velocity and acceleration
... A ball starts to roll down a ramp with zero initial speed. After one second, the speed of the ball is 2 m/sec. How long does the ramp need to be so that the ball can roll for 3 seconds before reaching the end? ...

Propelling a Paramecium: Recitation
... d. Solve the equation that you found in (c) for vT. How does vT depend on the applied force? How would vT change if the paramecium pushed harder on the fluid? e. It's not very realistic for the paramecium to start at constant velocity. Suppose the paramecium is starting from rest and starts to move, ...

... • When surfaces slide or tend to slide over one another, a force of friction resists the motion. Due to irregularities (microscopic bumps, points etc) in the surfaces. Friction also occurs with liquids and gases – eg. air drag Eg. Push a box across a floor, applying a small steady force. The box may ...

Lab Writeup Springs and SHM
... Many forces vary with position. That is, they can grow stronger or weaker as the position of the particle undergoing the force changes. One such example is the force exerted on a mass attached to a spring. As the particle is moved away from the attached spring, the spring will exert more force to re ...
