In the metric system, weight is measured in Newtons following the equation W = mg, where W is weight, m is mass, and g is the acceleration due to gravitational field On earth, this value is approximately 98 m/s 2 It is important to note that regardless how strong a gravitational field may be, an object that is in free fall is weightless In cases where objects undergo accelerationThis formula uses the fact that the weight of the vehicle is W = mg Work of forces acting on a rigid body The work of forces acting at various points on a single rigid body can be calculated from the work of a resultant force and torque To see this, let the forces F 1, F 2 F n act on the points X 1, X 2 X n in a rigid body · 5 mg/ mg = = % w/w You might check that the other tube wasn't 5 mg/g rather than for the whole tube That would be 05%, the same thing But if your description is correct, there is a 301 difference, and he has reversed which is stronger, quite a serious error, really

· In this formula, W = mg, one can find the mass by rearranging this formul = mThe formula for weight is given by w = mg As weight is a force its SI unit is also the same as that of force, SI unit of weight is Newton (N) Looking at the expression of weight we see that it depends on mass and the acceleration due to gravity, the mass may not change but the acceleration due to gravity does change from place to place To understand this concept let's take this exampleW = mg W = 4800 x 10 = Newtons The tension (T) in the cable acting upwards and given as 60 000N when the elevator starts to move upward, the net force equals the difference in the two forces Using the formula of force, T mg = ma 60 000 48 000 = 4800a 12 000 = 48 00a a = 12 000/4800 = 25 The maximum upward acceleration the elevator can have is 25 m/s 2
· Apply the formula to calculate the equivalent lunar weight and store it in a variable called weightOnMoon OUTPUT Display the weight on the Moon on screen Python Code Your Task Complete the above code to calculate and output the weight of the enduser on all of the following planets Planet / Celestial Body Gravity (in N/Kg) Moon 1622 Mercury 37 VenusAcceleration due to gravity is g; · To convert this to milligrams, use the fact that 1 g = 103 mg You will end up with 0005g ⋅ 103 mg 1g = 5 mg Since this represents the number of milligrams of solute present for every 1 mL of the solution, you can say that the solution has a concentration of concentration = 5 mg mL−1 −−−−−−−−−− The answer is
· According to the formula of momentum, Momentum (p) = mass (m) × velocity (v) p = m × v m = p / v m = 1230 / 15 m = kg Therefore, the mass of the bike is kg Newton's Second Law Equation F = m(vu)/t Numerical 1 A robot that has a mass of 5 kg starts moving from the rest The velocity of the robot further increases and reaches up to 'v' m/s, when a force of NM = mass of object;F N = m * g F * sin(x) where F is the value of the external force x is the angle between the surface and the

W = mg = Ahg Newton The pressure on the bottom is the weight per unit area p = W/A N/m2 It follows that the pressure at a depth h in a liquid is given by the following equation p = gh The unit of pressure is the N/m2 and this is called a PASCAL The Pascal is a small unit of pressure so higher multiples are common WORKED EXAMPLE 2Remember, W = mg The mass of the first body is 5 kg and so its weight is 5g N The mass of the second body is 3 kg and so its weight is 3g N Remember to mark in the normal reaction force, a consequence of Newton's Third Law Using Newton's Second Law on body A (horizontally) (F = ma) T = 5a (1) Using Newton's Second Law on body B (vertically) 3g T = 3a (2) Solving (1) and (2The weight of an object may be thought of as acting at a single point called its centre of mass Depending on the object's shape, its centre of mass can be inside or outside it The weight of an
