Newton’s First Law of Motion explains that objects in a state of uniform motion tends to remain in rest unless an external force is applied to it. Galileo’s concept of inertia is termed “Law of Inertia”. Law of Inertia‚ an object in motion will continue in the same motion unless acted by an outside force. Aircraft in flight is an example of First Law of Motion‚ four forces on an aircraft; lift‚ weight‚ thrust‚ and a drag. Consider the motion of an aircraft at constant altitude‚ we can neglect the

In the first graph‚ the golf ball flew extremely higher than the wiffle ball when bounced off of the basketball. Therefore‚ it makes the forces unbalanced and allows the smaller balls to bounce higher from the motion of the larger balls. In the second graph‚ the golf ball also bounced significantly higher than the wiffle ball when bounced off of the volleyball. This means the more mass the top ball has‚ the more force energy is transferred into it. There was more energy transferred into the golf

relates to physics is‚ the effects that can happen to a person when they are weightlifting with machines. Although easier to work with than free weights‚ weightlifting machines produce inertia effects that can double the force experienced by a user. Muscles and ligaments can be damaged by this sort of inertia-generated overload. To avoid injuries‚ coaches and therapists prefer that resistance remain constant throughout the range of a user’s movements; Conventional weightlifting machines

Synchronous tie exhibits the typical behaviour that as power transfer is gradually increased a maximum limit is reached beyond which the system cannot stay in synchronism‚ i.e.‚ it falls out of step. 2. The system is basically a spring-inertia oscillatory system with inertia on the mechanical side and spring action provided by the synchronous tie wherein power transfer is proportional to sin d or d (for small d; d being the relative internal angle of machines). 3. Because of power transfer being proportional

Dragsters use a combination of large wide tyres or the rear and small narrow tyres on the front this combination is used for the following reasons: <br> <br><b>The front wheels:</b> <br>The front wheels are very narrow. This is so a minimum of air resistance or drag affects the dragster with lower drag better acceleration an in turn a better top speed can be achieved all leading to a better pass (race time). <br> <br>Now lets try to understand the concept of air resistance and drag. A basic example

When you think of ballet dancing and ballet dancers you think of grace and beauty. While you watch a dancer dance you never think of the physics and mathematics behind their every move. Physics is described as a thing that is all about measurement‚ and that if you know the units of measurement that physics uses and how they work you will understand everything else you’ll learn about (Dennis and Moring 1). The textbook definition of physics is “the study of matter and energy and their relationships”
