Why you need large force to move box without wheels?
A large force is needed to move a box without wheels because of the friction between the box and the surface it's resting on. The friction creates resistance, making it harder to overcome and requiring more force to initiate movement. Adding wheels reduces the contact area and friction, making it easier to move the box with less force.
How do train wheels grip the track to ensure safe and efficient travel?
Train wheels grip the track using a combination of friction and weight. The weight of the train pressing down on the wheels creates a strong grip on the track, while the shape of the wheels and the materials they are made of help to increase friction and prevent slipping. This grip allows the train to travel safely and efficiently along the tracks.
What causes the forward force on a car?
The forward force on a car is caused by the engine applying power to the wheels, which creates friction between the tires and the road surface. This friction allows the wheels to push against the road and propel the car forward.
Why is it more efficient to move a box up a ramp on wheels than sliding it?
Moving a box up a ramp with wheels is more efficient because the wheels reduce friction between the box and the surface of the ramp, allowing for easier movement. Sliding the box directly on the surface creates more friction, making it harder to move the box and requiring more force.
What force allows a car's brakes to stop a car?
Friction between the brake pads and the rotors creates a force that slows down the car's wheels, ultimately stopping the car. This friction converts the kinetic energy of the car into heat energy, dissipating it into the environment.
How do brakes slow down a car?
The brake pads rub against your wheels(rotars) and creates more friction slowing the movement of the wheels.
What kind of friction is wheels rolling on a car?
kinetic friction, and this motion creates thermal energy from this friction. However the wheels moving on a car is directly created from the work of a combustion engine which creates multiple types of friction, chemical and thermal are the two major types.

Does salt create friction?
no, movement creates friction

Is there friction when you are are roller skating?
Yes- your body has friction with the air, and the wheels have friction with the floor.
Is there a lot of friction on an accelerating car?
Absolutely, as there is air resistance, the stickiness of the car's wheels, and the friction of the axles turning the wheels.
How do wheels reduce friction?
Wheels reduce friction by creating rolling motion instead of sliding motion. This reduces the amount of surface contact and friction between the wheel and the ground. Additionally, wheels can distribute the weight more evenly, further decreasing friction.
How does friction affect race cars?
it knackers up the tyres. this is because the wheels are moving at a phenomenal rate and creates friction on the tarmac. to get and understanding of what it feels like rub your hands together hard. now think of this 5000x a second.
