The velocity of an object that falls freely due to the earth gravity can be modeled by
Question:
m dv/dt = –mg + kv2
where m is the mass of the object, g = 9.81 m/s2, is and k is a constant. Solve the equation for v for the case m = 5 kg, k = 0.05 kg/m, 0 < t < 15 s and v(0) = 0 m/s. Make a plot of vas a function of time.

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
