Spring Forces and Simple Harmonic Motion
... If the only force doing work on an object is the spring force (conservative), its mechanical energy is conserved. If frictional forces also do work, the object’s mechanical energy decreases, and the SHM is called damped. If the frictional force is just large enough to prevent oscillation as the obje ...

... the magnitude of the velocity of the projectile at time t = 15.0 s (in mid-flight). Remember that for projectile motion, the x and y motions are independent, with y acceleration given by gravity and x acceleration zero. First let's figure out the vertical velocity of the projectile at t = 15.0 s. Fi ...

... Springs often provide a linear force (-k x) towards its equilibrium position (Chapter 10) Collisions often involve a varying force F(t): 0 maximum 0 We can plot force vs time for a typical collision. The impulse, Δρ, of the force is a vector defined as the integral of the force during the ti ...

Dynamics of Uniform Circular Motion
... In this case, the centripetal force is not merely the tension force in the string. Since centripetal force is always the net force acting on an object following a circular path, the centripetal force in this case is a combination of the tension force in the string and the weight of the ball. Notice ...
