WebIf there's no force such as friction or air resistance, objects would experience a constant acceleration, meaning they would be speeding up until reaching the speed of light all the time. Because if we are at a rest (0 velocity) and want to change our velocity we need a force. And that force wouldn't had a counterpart. WebHace 1 hora · Updated: 04/14/2024 03:52 PM EDT.

In common usage, the mass of an object is often referred to as its weight, though these are in fact different concepts and quantities. Nevertheless, one object will always weigh more than another with less mass if both are subject to the same gravity (i.e. the same gravitational field strength). In scientific contexts, mass is the amount of "matter" in an object (though "matter" may be difficult to define), but weight is the force exerted on an object's matter by gravity.
