Does gravity exert the same force on all falling objects?
No. Gravity can be thought of as a force, but that is due to its effect on anything that possesses mass and/or energy. The effect that gravity exerts on any object is proportional to the amount of mass that is responsible for the presence of gravity and is also proportional to the amount of mass possessed by the object experiencing that gravitational presence. Therefore a gravitational field will exert a greater 'force' on a greater mass. However, mass also possesses the characteristic of inertia, which is a measure of resistance to any change to a state of motion - which effectively is a resistance to the effect of gravity. Inertia is also proportional to mass. What this means is that the greater the mass, the greater the pull it experiences due to gravity but at the same time, the greater is its resistance to that pull. Hence all falling objects experience the same acceleration due to the effect of gravity which is not the same as the force. All objects fall at the same rate. ========================= (Note: Gravity does not exert the same force on all objects, which is the reason why big people "weigh" more than smaller people do on the same planet.)
Are objects lighter in water than in air?
They are not really lighter, they only seem lighter. Objects weigh the same in water as in air, but in the water, there is an additional force, of the water pushing the object up.
What are tow forces?
Tow forces refers to the amount of weight that a vehicle can tow in ratio to its weight. For example, a tow truck may weigh 2 tons, but exert a tow force of 4 tons.
Why an object underwater feels lighter than it is in air?
There is a force called upthrust coming from the water. this pushes objects upwards, making the resultant force lower, which means they seem to weigh less.
What determines the mass of an objects?
The only "weigh" to determine the mass of an object is to compare it with the mass of a known object. The mass of an object is determined by force and acceleration.
Can you put more force on an object than you weigh?
No, it is not possible for Humans. However, some organisms, such as ants, can exert a force many times its own weight.

What objects can you weigh using pounds?
None. Pounds are a measure of mass, weight is measured in pounds-force.
Do objects on other planets weigh the same as they weigh on Earth?
No. Weight is the measure of how much force a planet pulls an object, that force is determined by the planet's mass and radius, and each planet has a different mass and radius.
Why do you weigh different on objects in space?
Is your question "what do you weigh different objects on in space...", or "why would you attempt to weigh an object in space"...?
How many Newtons would a football weigh if it had a mass of 400 gHow many Newtons?
Something with a mass of 400g would exert a force of 3.9228 newtons.

How does the force due to gravity on Mars compare to the force due to gravity on Earth?
The acceleration of gravity at the surface of Mars is approximately 3.7 m/s2. Earth's acceleration is 9.8 m/s2 on average. The force that gravity would exert on an object is dependent on its mass.
What is the force that dictates that objects weigh more at the equator than at the poles?
Well the above question is not true, The same object will weigh less at the equator than at the poles (of Earth). The force is the force of gravity and the effect is because the object placed at the poles will be nearer the center of the Earth than at the equator because the Earth is an Oblate Spheroid.
