These particular materials reduce the mass of the plane and contribute to making the plane become airborne. For example‚ let’s say‚ a plane is accelerating at a speed of 7.1 m s-2 and its total mass is 1.15 x 105 kg‚ for us to figure out the relative force we need to use this formula‚ F = ma. So F = (2.26 x 105) x 7.1= 8.17 x 105 N. The previous formula is Newton’s Second Law of motion and is stated as ‘Force equals mass times acceleration’. As you can see there needs to be a great amount of

Q2: What do you mean by a body in rest? Answer: A body is said to be at rest‚ if it does not change its position with respect to a fixed point in its surroundings. Q3: Are motion and rest absolute or relative? Explain with an example. Answer: No these terms rest and motion are relative. For example‚ a person inside a car‚ carrying a ball in his hand will see the ball is at rest. While for another person‚ outside the car will see the ball is also moving.
