In a pendulum, the gravitational force acts as the restoring force. When the pendulum is at the maximum displacement position, the force that... View Article
According to Newton’s second law of motion, when a constant force is applied to an object it causes the body to accelerate in the direction of... View Article
The negative sign in Hooke's law shows that the restoring force exerted by the spring is in the opposite direction to the force that causes the... View Article
The spring constant cannot be negative. Spring constant will always be a positive value. The negative sign in Hooke's law shows that the... View Article
As the length of the spring is increased spring constant decreases. Spring constant and length are inversely proportional. If the spring is cut... View Article
Spring constant decreases with an increase in temperature. The definition of spring constant can be got from Hooke’s law. The unit of spring... View Article
The entropy will never decrease, it will remain constant or increase. Let us take the example of heat transfer, heat is spontaneously transferred... View Article
Yes, heavier objects have more inertia. It is difficult to move and stop objects with greater mass. The heavier objects will resist change more... View Article
According to Newton’s law of inertia, an object tends to resist any change in its state of rest or uniform motion unless it is acted upon by an... View Article
