That's a formula that shows the relationship between three quantities ... weight, mass, and acceleration. If you know any two of them, then you can use this formula to find the one you don't know.
Examples:
==> I have a rock with 2 kilograms of mass. The gravitational acceleration on Earth is 9.8 m/s² . How much does my rock weigh on Earth ?
Weight = (mass) x (grav acceleration) = (2 kg) x (9.8 m/s²) = 19.6 newtons (about 4.41 pounds)
==> My brother weighs 770 newtons (about 173 pounds) on Earth. What is his mass ?
Weight = (mass) x (grav acceleration)
770 newtons = (mass) x (9.8 m/s²) Divide each side by 9.8 m/s²: 770 newtons / 9.8 m/s² = mass
78.57 kilograms = mass
==> When I went to the Moon, I took along my 2-kilogram rock. I weighed my rock on the Moon. It weighs 3.25 newtons (about 0.73 pound) there. What is the gravitational acceleration on the Moon ?
Weight = (mass) x (grav acceleration)
3.25 newtons = (2 kg) x (acceleration)
Divide each side by 2 kilograms: (3.25 newtons)/(2 kg) = acceleration
The temperature of an object increases when the molecules that make up that object move faster. Thermal energy is energy possessed by an object or system due to the movement of particles within the object or the system.
The function of the digestive system is digestion and absorption. Digestion is the breakdown of food into small molecules, which are then absorbed into the body.
