... Yes, the direction of velocity is changing. Centripetal acceleration is provided by the tension in the string. The centripetal acceleration is different in the two cases presented, therefore, the tension will be different Note that the radius has not changed in the two conditions Note also that angu ...

Force and Motion
... When the fly hit the truck, it exerted a force on the truck (only for a fraction of a second). So, in this time period, the truck accelerated (backward) up to some speed. After the fly was squashed, it no longer exerted a force, and the truck simply continued moving at constant speed. Follow-up: Wha ...

... object 2 is equal in magnitude but opposite in direction to the force exerted on object 2 by object 1. The classic way of saying this is, “For every action there is an equal and opposite reaction”. Newton’s third law simply says that forces come in pairs. You push on a wall and the wall pushes on yo ...

Vectors
... Velocity and acceleration vectors Displacement is our prototype vector. Velocity is derived from displacement by dividing it by an interval of time. The result of dividing a vector by a scalar is a vector. Likewise, dividing a vector representing velocity difference by a time interval gives a vector ...

6-2 Equilibrium
... Consider the only simplifying situations: the forces only act on the body lie in the xy plane. then the only torques that can act on the body must tend to cause rotation around an axis parallel to the z axis. With this assumption, we can eliminate one force equation and two ...

... For medium speeds, (not real slow and not real fast), the coefficient for air resistance, b, can be expressed as: b = (1/2)*C*Across-section*ρ Where C is a constant that depends on the shape (for a sphere, C = ½), A is the cross-sectional area perpendicular to the velocity, and ρ is the density of t ...

... we can deduce that the period of the simple harmonic motion of an ideal spring is given by T 2 m/ k , where m is the mass at the end of the ideal spring and k is the spring constant. We can deduce from Equations 10.5 and 10.16 that, for small angles, the period, T, of a simple pendulum is given b ...
