Question:
A small object with mass m = 0.0900 kg moves along the +x-axis. The only force on the object is a conservative force that has the potential-energy function U(x) = -αx2 + βx3, where α = 2.00 J/m2 and β = 0.300 J/m3. The object is released from rest at small x. When the object is at x = 4.00 m, what are its
(a) Speed and
(b) Acceleration (magnitude and direction)?
(c) What is the maximum value of x reached by the object during its motion?

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.
