A bulldozer drags a 252 kg long along the rough horizontal ground. The cable attached to the log applies a 525 N force at an angle of 30.0 degrees above the ground. The coefficient of kinetic friction between the log and the ground is 0.150. Assume the direction of motion is +x and upwards is +y. What is the normal force acting on the log? What kinetic friction force is acting on the log? (With proper sign) What is the acceleration of the log?
Gravitational force
In nature, every object is attracted by every other object. This phenomenon is called gravity. The force associated with gravity is called gravitational force. The gravitational force is the weakest force that exists in nature. The gravitational force is always attractive.
Acceleration Due to Gravity
In fundamental physics, gravity or gravitational force is the universal attractive force acting between all the matters that exist or exhibit. It is the weakest known force. Therefore no internal changes in an object occurs due to this force. On the other hand, it has control over the trajectories of bodies in the solar system and in the universe due to its vast scope and universal action. The free fall of objects on Earth and the motions of celestial bodies, according to Newton, are both determined by the same force. It was Newton who put forward that the moon is held by a strong attractive force exerted by the Earth which makes it revolve in a straight line. He was sure that this force is similar to the downward force which Earth exerts on all the objects on it.
