Assuming there is no air resistance, if an object starts at a speed of 11.2 km/sec, it can escape the gravitational field of Earth. This "escape velocity" is different for different planets, moons, etc.

To lift 100 pounds against gravity, you would need to apply a force of 100 pounds. This accounts for overcoming the force of gravity pulling the object downward. If the object is being lifted vertically at a constant speed, the force required would be equal to the weight of the object.
When an object is thrown upwards, it loses 9.8 meters per second of speed due to gravity acting against its motion. This is the acceleration due to gravity on Earth, which causes the object to slow down as it moves upward.
If the weight is 300 pounds, you will need to apply a force of at least 300 pounds to lift it against the force of gravity. This force is known as the weight of the object.
The work required to lift the concrete block can be calculated using the formula: work = force x distance. If the concrete block weighs 1 kg, then the force required to lift it against gravity can be calculated as force = mass x gravity, where gravity is approximately 9.81 m/s^2. So, the work done would be work = 1 kg x 9.81 m/s^2 x 3.8 m.
To move a 5kg stone for 1km, you would need to overcome both the force of friction and the force required to lift the stone against gravity. The force needed would depend on the surface and incline. The total force required can be calculated using the work-energy principle.

Gravity is measured, not in terms of speed, but of acceleration. For example, Earth gravity is 9.8 meters/second2. 110 times that much would be called, informally, "110 g".

Gravity. When you're climbing up a hill, you're pretty much competing against gravity.

Poo is subject to the force of gravity, 9.8 m/s2.
The work done against gravity is calculated using the formula: work = force x distance. In this case, the force against gravity is the weight of the box, which is mass x gravity. So, work = (16 kg x 9.8 m/s^2) x 0.50 m = 78.4 J.
