gravity pulls down a rocket
Gravity acts as a force that pulls the firework downward throughout its ascent. As the firework is launched, it initially overcomes gravity due to the thrust generated by the propellant. However, as it rises, gravity gradually slows its ascent until it reaches its peak height, where the upward momentum is completely countered by gravitational force. After reaching this apex, gravity then causes the firework to fall back down, leading to its eventual explosion at the peak.
As the firework rocket ascends, gravity is continually acting on it, pulling it down towards the Earth. However, the rocket is propelled upwards by its internal fuel source, counteracting the force of gravity. Once the fuel is depleted and the rocket reaches its peak height, gravity will then slow it down and pull it back towards the ground.
Exactly the way you do it when you walk up stairs ... use your engines tocreate a force greater than your weight and opposite to the force of gravity.
When a firework rocket is on its way down, gravity exerts a constant downward force, pulling it towards the Earth. This force causes the rocket to accelerate downward at approximately 9.81 m/s², increasing its velocity as it descends. As the rocket falls, air resistance also acts on it, opposing the force of gravity and eventually leading to a terminal velocity where the forces balance out. Ultimately, gravity is the primary force that governs the rocket's downward motion during its descent.
Gravity affects our daily lives by keeping us grounded on the Earth. It influences our movements, the way objects fall, and even the flow of fluids in our bodies. Without gravity, we would float away into space.
The only reason would be gravity.
The vehicles used on the Moon were designed with the Moon's gravity in mind. They would not function correctly on Earth. So the answer is that the Moon's gravity affects the lunar rovers in the same way as gravity affects cars and other vehicles on Earth.... it is what keeps them on the surface, and prevents from from floating off into space.
Gravity affects ice in the same way it affects other objects, pulling it towards the center of the Earth. It causes ice to have weight, just like any other material. Gravity can also deform ice, leading to the flow and movement of glaciers over time.
Glass flooring or any other material does not "have gravity". Gravity is a force that affects all materials in exactly the same way. Our experience of gravity is that it pulls object and materials towards the ground. A glass floor will be pulled downward in the same way that any other flooring will be.
no way
No, lighting a firework is not irreversible. Once ignited, the firework will burn and explode, but the process itself is not permanent. The chemical reactions that produce the light and sound are temporary and do not alter the firework in a permanent way.
An object's weight in air is the same as its weight in a vacuum. This is because weight measures the force of gravity acting on an object, and gravity affects objects in air and in vacuum in the same way.
