It all depends on what it is made of. Some made of metal will sink and others made of wood will not. Also the amount of air inside the enclosed part will also determine if it will or will not float.
Not necessarily. The distance a toy car travels depends on various factors like the force applied, the surface it's moving on, and the friction. A heavier toy car may have more momentum, but a lighter toy car may be able to move faster with less effort.
Mechanical energy is not produced in a toy car. Instead, the toy car converts potential energy (stored energy) into kinetic energy (energy of motion) as it moves. The mechanical energy in the toy car comes from the energy used to make it move, not from being produced within the toy itself.
You can power a toy car by using batteries or rechargeable battery packs. The batteries supply electrical energy to the electric motor in the toy car, which then converts the energy into motion to make the car move.
A heavier toy car is better to go down a ramp and make a jump better than a light car because the heavier the toy car is, the faster gravity will force it to roll down the ramp, and with all its speed, be able to make the jump. Of course, you wouldn't want to make the toy car so heavy so that it barely or doesn't move at all. Just like drops of water when it's raining outside and a few drops hit your window. The heavier drops drip off faster than the smaller ones, and that goes the same with cars, too.
The distance a toy car can travel on a ramp depends on factors like the incline of the ramp, the initial velocity of the car, and any friction present. In general, a toy car on a ramp can roll for a distance equivalent to the length of the ramp if there is no significant friction or obstacles in its path.
That depends what it's made of ! A metal one will sink, but a wooden or plastic one will float.
If its density is less than 1.00 it floats. Otherwise it sinks.
A plastic toy sinks if its density is greater than that of the water it is in. Density is defined as mass per unit volume; if the toy's mass is heavy relative to its size, it will displace less water than its own weight, causing it to sink. Additionally, if the toy has air-filled cavities or is designed to float, it may remain on the surface instead.
There is no difference on how well a toy boat will float in water depending upon the temperature. The ability for an object to float is if it can displace more than its own weight in water, which doesn't depend on the temperature of the water.
Put an Alka-Seltzer tablet inside before you put it in the water - the expanding gas from the tablets when the water hits them will force the water out and float it. Old toy submarines used the same thing when I was growing up in the '60's - make sure you've got a mild weight on the keel to help it sink, but not too heavy. Usually coins will work.
Yes it does because depending on the materials of the boat and how much their mass is can change the buoyancy of the toy boat. Boat can be designed to have less volume in order for it to have less density and be able to float. So if the material's mass is alot if can make the boat sink. If the material's mass is not alot then it can help the boat float. If the shape is designed to have more volume than mass it will float. If not then it will sink.
You fill the bottom of the boat with water
Buoyancy
Two axles and 4 wheels on a board car-like, pump up water rocket attached to the board lengthwise. You have a water powered toy car
You take a sponge and tooth pick and put them togather
get some water from the sink then put it in a toy cup then put your Lego into the cup
A toy boat.
