Question:
A sphere is falling in a liquid. Calculate the terminal velocity in units of m/s. The projected area (i.e., reference area) is 10 cm2. The coefficient of drag is 0.4. The mass of the sphere is 70 grams. The specific gravity of the liquid is 1.2. Choose the closest answer (m/s):
(a) 1.3,
(b) 1.7,
(c) 1.8,
(d) 1.9, or
(e) Above 2.1.

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.
