You weigh 526 N on earth. Planet X has twice the mass of Earth and the radius of Earth. What is your weight in newtons on planet X? a) An object has a mass of 33 kg. The acceleration of gravity is 9.8 m/s^2. What is its weight on the earth?...
Density is a measure of how much mass there is in a substance per unit volume. The density of liquid water is 1 g/mL, meaning in every milliliter of water there is 1 gram of water. Answer and Explanation: The mass of 1 L of water is 1000g and the weight in Newtons...
understand what SHISHKABOB said in his post :) Dave Hehe, just checking my understanding. Weight is the force due to gravity and mass is the amount of matter in an object? And since weight is the force due to gravity, it is considered a force. And this force is measured in Newtons....
In the absence of air (no air resistance), all things fall with the same acceleration due to gravity; this is Newtons's Second Law. In real life, there is air resistance. We will explore the variables of the force of air resistance in some simple experiments. Air Resistance and Mass ...
The gravitational constant (G) is a fundamental constant in physics that describes the strength of the gravitational force between two objects. It has a value of approximately 6.67430(15) x 10-11 Newtons (m2/kg2). Gravity and Everyday Objects The gravitational attraction between everyday objects...
Newtons Third Law Motion Introduction to Newton’s Third Law of Motion Newton’s first law of motion implies that any object cannot start, stop, or change its direction by itself. The object must require certain force from the outside world to cause such a change. Such property of massive ...

In physics, weight is equal to the force due to gravity acting on an object and it is measured in Newtons (N). The weight of an object can be found by multiplying its mass in kilograms (kg) by the acceleration due to gravity on Earth (10m/s/s)....
