Research Question How does spacing between dominoes affect the average velocity of the dominoes? Increasing space between each domino will decrease its velocity‚ decreasing the space will increase its velocity. Force at which it hits next dominoes is increased it will take longer for it hit‚ acceleration is constant‚ the longer it has to travel‚ the longer it will take to hit. According to Newton’s first law every object in a state of uniform motion tends to remain in that state of motion

Physics of Sports A sport isn’t just about winning; it is also about strategy‚ how the game is played‚ and performance of the athletes. Physics is the last topic many people associate with sports. However‚ physics can be applied to every aspect of any sport‚ which is a study referred to as Sports Science. Components of this study include gravity‚ projectile motion‚ acceleration‚ force‚ vectors‚ etc. With new technology that physics in sports introduce‚ more possibilities of physical science can

RETREAD RUBBER - MARKET ANALYSIS Introduction 1. In the manufacture of a new tyre‚ about 75% of the manufacturing cost is incurred in Tyre Casing and remaining 25% in the Tread (The portion of the tyre which meets the road surface).Hence‚ by applying a new Tread over the body of the worn out tyre‚ a fresh lease of life is given to the tyre‚ at a cost which is less than 30% of the price of a new tyre. This process is termed as Tyre retreading and the materials used for process are known as

and planes. Wheelchair ramps are used to allow people in wheelchairs to get over vertical obstacles without exceeding their strength. Escalators and slanted conveyor belts are also forms of inclined plane. In a funicular or cable railway a railroad car is pulled up a steep inclined plane using cables. Inclined planes also allow heavy fragile objects‚ including humans‚ to be safely lowered down a vertical distance by using the normal force of the plane to reduce the gravitational force.
