through biomechanical analysis and watching different strategies in slow motion to provide advanced techniques. There are many different techniques used to clear the bar but the prior approach and motor behavior in the air is most significant. Acceleration and timing of the approach are crucial for a good jump. You must be conscious of body position‚ take-off foot and leaping upwards among other things when taking off. In the video there are numerous positions of the arms presented‚ the use of the

physics formulas falling in mechanics domain. Motion in One Dimension The physics formulas for motion in one dimension (Also called Kinematical equations of motion) are as follows. (Here ’u’ is initial velocity‚ ’v’ is final velocity‚ ’a’ is acceleration and t is time): * s = ut + ½ at2 * v = u + at * v2 = u2 + 2as * vav(Average Velocity) = (v+u)/2 Momentum‚ Force and Impulse Physics Formulas for momentum‚ impulse and force concerning a particle moving in 3 dimensions are as follows

physically meaningful. Answers (a)‚ (b)‚ and (c) must be meaningless since quantities can be added or subtracted only if they have the same dimensions. According to Newton’s second law‚ Force = mass × acceleration . Thus‚ the units of Force must be the product of the units of mass (kg) and the units of acceleration ( m s 2 ). This yields kg ⋅ m s 2‚ which is answer (a). The calculator gives an answer of 57.573 for the sum of the 4 given numbers. However‚ this sum must be rounded to 58 as given in answer (d)

Centrifuges work by using the sedimentation principle. Said principle is when centripetal acceleration is used to separate the lower and higher dense particles in a substance. 3. Once centrifuged‚ the supernatant is to be removed and labeled accordingly in a separate vessel. Supernatant is the liquid above the sediment after a solution has

(Term I) 10a Gravitation IMPORTANTIMPORTANT NOTES NOTES IMPORTANT NOTES 7. Acceleration due to gravity of the Earth : The acceleration with which the bodies fall towards the earth is called acceleration due to gravity. Its average value is 9.81 ms–2. 8. Variation of acceleration due to gravity. (i) Acceleration due to gravity changes with the change in distance from the centre of the earth. (ii) Acceleration due to gravity is maximum at the poles of the earth. Its value decreases as we move
