More commonly, air friction has terms proportional to the square or even higher powers of the velocity. For linear velocity dependence the resistance force can be written. f resistance = -bv . If this resistance is the only force acting, then Newton's second law becomes. Analyze motion.



Kinetic friction acts on an object in relative motion, while static friction acts on an object or system at rest relative to each other. The maximum static friction is usually greater than the kinetic friction between the objects. Imagine, for example, trying to slide a heavy crate across a concrete floor.



The square of a planet's orbital period is proportional to the cube of the length of the semi-major axis of its orbit. The elliptical orbits of planets were indicated by calculations of the orbit of Mars. From this, Kepler inferred that other bodies in the Solar System, including those farther away from the Sun, also have elliptical orbits. The.



An artificial satellite is moving in a circular orbit with a radius of 42250 km. Calculate its speed if it takes 24 hours to revolve around the earth? Answer: The orbit’s circumference is equal to 2πr. The orbit’s circumference is equivalent to 2×π×42250. The orbit’s circumference is 265330 kilometers. The orbit takes 24 hours to complete.

Uniform circular motion is a specific type of motion in which an object travels in a circle with a constant speed. For example, any point on a propeller spinning at a constant rate is executing uniform circular motion. Other examples are the second, minute, and hour hands of a watch.



Two trains, 250 metres and 150 metres long respectively, are running on parallel lines. If they are running in the same directions, the faster train crosses the slower train in 40 seconds. If they are moving in the opposite direction they pass each other in eight seconds. What is the speed of the slower train?

A body of mass 5 kg if moving with a velocity 10 m / s. find its kinetic energy. find the ratio of initial kinetic energy and final kinetic energy if (i) its mass is doubled (ii) its velocity is made three times.



In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s 2 .
