In Newtonian physics‚ free fall is any motion of a body where its weight is the only force acting upon it. In the context of general relativity‚ where gravitation is reduced to a space-time curvature‚ a body in free fall has no force acting on it and it moves along a geodesic. The present article only concerns itself with free fall in the Newtonian domain. An object in the technical sense of free fall may not necessarily be falling down in the usual sense of the term. An object moving upwards

5 of the biggest unsolved mysteries in physics The mysteries of the universe are as vast and wide as existence itself. Throughout history‚ mankind has searched and struggled to find the answers tucked away inside the universe and everything we see around us. As Deep Thought said in the Hitchhiker’s Guide to the Galaxy‚ "I think the problem‚ to be quite honest with you‚ is that you’ve never actually known what the question is." True‚ we have yet to come up with the answers to life‚ the universe

and excitement of physics Let Us Learn About Scope and excitement of physics Physics is exciting because‚ trains us in problem solving‚ It helps us to have an analytical outlook‚ to observe rather than see things. Everything is explained on the basis of the cause effect relationship‚ which helps us think logically and decide rationally Whether or not‚ a students of plus two continue to learn Physics‚ the basic problem solving skill he has acquired during the PlusTwo Physics course will remain

Investigatory Projects in Physics Repulsorlifts as a Method of Stable Magnetic Levitation | Repulsorlifts were used in the study to find out if they can be used to replace the wheels of a conventional car. It was hypothesized that it will be able to lift a car using magnetic repulsion forces. The different magnets were tested individually with the usual tests for magnetic strength‚ size‚ and temperature increase‚ which were done in the preliminary testing. The prototype road and car were then constructed

between the armor of the enemy knights also they were used to throw hot tar to attack there enemies. It was also used to launch infected bodies into enemy camps to spread disease. Although they are very hard to create‚ they use very simple forms of physics to complete their task of destruction. The catapult has a basket or cup on the end of a movable arm strong enough and large enough to hold the weight of the object it is intended to hurl. Tension is applied to the arm‚ whether that be applied by
