Name:Date:5.15.1 Mass, Weight, and GravityHow do we define mass, weight, and gravity? How are mass, weight, and gravity related?The weight equation W = mg shows that an object’s weight (in newtons) is equal to its mass (in kilograms) multiplied by the strength of gravity (in ...
A tool used to measure weight or force balance a tool used to measure mass Distance How close or far away one thing is from another Mass and Distance What two factors affect gravitational attraction? The larger the mass the stronger the gravitational attraction the smaller the mass the smaller...
sSouth Poleis slightly more than its weight at theEquatorbecause the polar radius of the Earth is slightly less than the equatorial radius. Though themassof an object remains constant, its weight varies according to its location. The smaller mass and radius of the Moon compared with those of ...

Specific Weight common Materials Material Properties Example 1: Density of a Golf ball A golf ball has a diameter of 42 mm and a mass of 45 g. Thevolumeof the golf ball can be calculated as V = (4/3) π (42 [mm] * 0.001 [m/mm]/2)3= 3.8 10-5[m3] ...
Weight and mass The weight W of a body can be measured by the equal and opposite force necessary to prevent the downward acceleration; that is Mg. The same body placed on the surface of the Moon has the same mass, but, as the Moon has a mass of about 1/81 times that of Earth and...
What is meant by gravity and weight, Explore the difference between mass and weight, How to calculate weight using mass and gravitational field strength, gravitational acceleration, Explore how the weight of an object depends on its location, examples a
gravity与weight有什么区别?我想知道这两个词有什么区别 我们的课本上有weight=mass×acceleration due to gravity 我想知道这个公式在中文里是什么意思 答案 我先解释gravity 吧.gravity 就是地心引力,也可以叫做gravitational pull,是地球对其他物体所产生的吸引,也就是我们所说的acceleration(重力加速度),通常就是g...
