Can an object ever have zero weight
WebTwo objects of the same mass can weigh differently. To gain weight, one must put on more mass. The weight of an object can be measured in kilograms. The weight of an object is equal to the force of gravity acting upon the object. When a chemistry student places a beaker on a balance and determines it to be 84.3 grams, they have weighed the beaker. WebNewton's first law says that if the net force on an object is zero ( \Sigma F=0 ΣF = 0 ), then that object will have zero acceleration. That doesn't necessarily mean the object is at rest, but it means that the velocity is constant. In other words, constant zero velocity—at rest—or constant non-zero velocity—moving with a constant velocity.

WebOct 18, 2024 · Yes. Free fall is defined as “any motion of a body where gravity is the only force acting upon it.”. In the vacuum of space, where there are no air molecules or supportive surfaces, astronauts are only acted upon by gravity. Thus, they are falling towards Earth at the acceleration of gravity. WebIn theoretical physics, negative mass is a hypothetical type of exotic matter whose mass is of opposite sign to the mass of normal matter, e.g. −1 kg. Such matter would violate one or more energy conditions and show some strange properties such as the oppositely oriented acceleration for an applied force orientation. It is used in certain speculative hypothetical …
WebAnswer (1 of 2): Sure. Weight and mass are two different concepts, and the formulas for momentum and kinetic energy use mass. An astronaut orbiting the earth is “weightless” … WebDec 17, 2014 · Zero acceleration implies a constant velocity. Constant velocity also includes zero velocity as a special case. So an object in equilibrium can either have zero velocity or a constant non-zero velocity. Static Equilibrium: When the net force acting on an object is zero and if the object is not moving, then it is called static equilibrium.
WebOct 28, 2024 · Best Answer. Copy. i just found it out: No material object can ever have zero mass OR zero weight. But since its weight depends on the mass of other masses … WebThe weight may be well secured, ... The gravitational potential energy could even be negative if the object were to pass below the zero point. This doesn't present a problem, though; we just have to be sure that the same zero point is used consistently in the calculation. ... we just have to be sure that the same zero point is used consistently ...
