Which would have more friction, a car traveling down a street or a toy remote-control car traveling on the same street? Why?

The car will have greater friction because it has greater mass.

Given that the coefficient of friction is obtained as;

μ = F/R

Where;

F = force acting on the object

R = normal reaction

μ = coefficient of friction

Friction is the force that acts when two bodies slide over each other. The greater the mass of the object, the greater the magnitude of friction between them. Since the car has a much larger mass than the remote, the car experiences greater friction than the remote.

Explanation:

Think about the formula for friction: it's the coefficient of friction mu × the normal force.

The normal force is F = ma, force = mass × acceleration.

So the more mass an object has, the more friction it will have. The car will have more friction than the toy car.
