Describe Increasing and Decreasing Friction
Friction is inextricably related to our daily lives. Friction can be increased in necessity; again friction can be decreased too in necessity. How friction can…
Explain Effects of Friction on Motion
Friction has an enormous influence on the motion of an object. Friction is a kind of resistive force which slows down the motion of a…
Explain Types of Friction
Generally there are four types of friction. Static friction Sliding friction Rolling friction Fluid friction Static: Static friction is the friction between two surfaces that…
Describe Friction and Force of Friction
We are familiar with friction in various ways in our daily lives. From Newton’s first law of motion we know that if no force acts…
Mathematical Example: Newton’s 3rd Law
Example 1: A force of 2000 N acts on a body of mass 20 kg for a time of 0.1 s. What is the change of…
Eplain Action and Reaction Force of Newton’s Third Law
Whenever a force acts on one body, at that time an equal and opposite force acts on some other body. This matter is generally stated…
Mathematical Example: Newton 1st Law
Example 1: What is the force to be applied to a mass of 50 kg to produce an acceleration of 4 ms-2 ? Solution Here,…
Relation between Force and Acceleration- Newton’s Second Law
Newton’s first law gives qualitative definition of force. Newton’s second law gives the equation for the measurement of force. From Newton’s second law we know…
Explain Effect of Force on Motion
Here explain some common effect of force on motion: A force can cause a stationary object to start moving. What happens when a stationary football…
