Formula for friction force in Physics with examples

The acceleration of a moving object depends on the net force acting on it. Therefore, the net force is an important quantity to study the dynamics of an object. In another article, we discussed equations for different types of Forces. In this article, I’m going to explore the Force of Friction in detail – its … Read more

Formula of Change in Momentum and Impulse

Momentum is a physical state of an object when it is in motion. A moving car cannot be stopped immediately after applying the break. It stops after moving a little distance because of its momentum. The position and momentum of a mechanical system describe the entire dynamics of the system. Therefore, the study of momentum … Read more

Differences between Mass and Weight of a body

Weight and Mass are not the same physical quantity. They have different units and dimensions. However, they are related to each other. In this article, I’m going to explain how is weight different from Mass and how to get weight from the mass of an object. Differences between Mass and Weight Here are some differences … Read more

Contact forces – definition, examples & equations

Newton’s second law of motion tells that a sufficient amount of net force can move an object from one place to another. For example, If you push an object placed on the floor, it will go away. Similarly, if you pull it, it will come closer to you. In either case, you have to touch … Read more

Translational Motion – equations, definition, types, examples

A particle is said to be in motion if it changes its position with time. The particle may go straight, may move in a circular path, may spin around an axis, or may roll on the floor. Considering these different ways of changing its position, Scientists have said that a particle can have three types … Read more

Equations for Force in Physics | definition formula unit

We have discussed Newton’s three laws of motion in other three articles. We get the definition of force from Newton’s first law of motion and the formula or the equation of force was derived from Newton’s second law of motion. Again, the third law gives an idea for the law of conservation of linear momentum. … Read more

Projectile Motion Equations in Physics

Equations for the linear motion and free fall are known to all. Using these equations one can find the position, velocity, acceleration and energy of a particle moving in a straight line with a constant velocity or constant acceleration. If we throw an object at an angle with respect to the ground, it will not … Read more

Work done by tension force – formula and derivation

In another article, we discussed the tension of a string or rope. We found that the tension of a string is a kind of force. Again, we know that a body can move due to the application of external force. So, the work done on a body depends on the force acting on it. Then, … Read more

How to find tension in a string? | Tension formula in physics

If you drop a ball from the roof of your house, the ball will fall under gravitational force. Now, attach the ball to an end of a string and fix the other end of the string somewhere on the roof. Then drop the ball from the roof again. This time the ball will be hanging … Read more

Derive Newton’s first law from second law – prove

We already have discussed Newton’s first law and second law in other articles. These two laws deal with the motion of any particle in classical limit. First law gives the cause of motion and the second law gives the measurement of the force required to apply to make a particle in motion. That means these … Read more
