Force 4.3
Weight is a gravitational force.You can find weight by w=am. In order to find weight, you have to multiply force of gravity(acceleration), by the mass to get the gravitational force(weight). For example, if a objects mass was 1 kg, and this object was on earth, you would multiply 1 times -9.81 m/s squared, because it is earths gravitational force(acceleration). So the objects weight is -9.81 N.
