For the car to start moving, it has to have a force applied to it. Once it is moving, and assuming frictional forces can be ignored, it will continue to move in a straight line.
So, you need something to get it started, and you are not allowed to use gravity, electricity, a motor running on combustible liquids or having someone pushing/pulling it? Mmm.
Is wind power allowed? Put a sail on top of your car and let the unbalanced pressure of the air on each side of the sail provide a net force.
Solar power usess electricity so I guess that's not allowed?
Getting a little extreme, but what about solar pressure? This is the momentum converyed to an object from photons of light. It is the same principle that explains why the tails of comets always point away from the sun. The momentum is so small, it wouldn't get your car moving very fast however!!!
Forces can act by pushing or pulling on an object, causing it to accelerate or change its motion. They can be gravity pulling an object down, a person pushing a box, or a magnetic force attracting iron objects. Forces can also act at a distance without physical contact, such as with electromagnetic or gravitational forces.
Isometric exercise involves pushing and pulling against an immovable object without joint movement. It helps strengthen muscles without changing their length.
wind or moving water
Going downhill, it's gravity. Going up long grades, there's a chain which grabs onto a hook on the bottom of the lead car.
No, a scale measures weight, which is the force of gravity pulling you toward the center of the Earth. Without gravity, there would be no weight to measure.
The concept of it is to fling heavy stuff far without a lot of effort of pushing it or pulling it
An object reaches its terminal velocity when the force of gravity pulling it down is equal to the air resistance pushing it up. At this point, the object stops accelerating and falls at a constant speed without gaining more velocity.
carry it Unless you also hand-made an engine for the vehicle.
In a gravity-less environment, an object would have no weight because there is no gravity pulling it down. Weight is the force of gravity acting on an object, so without gravity, there is no weight.
Gravity is a force of attration.It is a pulling matter.Gravity holds up the earth without gravity we would be having comets every single day ,it holds things in place.
An object suspends in a liquid when the density of the object is equal to the density of the liquid. This results in a condition where the buoyant force pushing up on the object is equal to the force of gravity pulling it down, allowing it to remain suspended in the liquid without sinking or floating.
Objects fall down due to the force of gravity pulling them towards the Earth's center. Objects don't appear to move up on their own because they need a force stronger than gravity, such as a person or a machine, to counteract gravity and lift them up. Without such a force, objects will naturally fall towards the Earth.
