Why is high friction good for car drivers?

Use the words 'friction' and 'motion'.

It increases the friction between the tyres and the road and prevents the change in motion of the car, for example: to stop it from skidding.

What is the definition of mass and weight?

The mass of an object is a measure of the amount of matter it contains.

Weight is a downward force.
