Front

Define friction in the context of motion.

Back

Friction is the resistance that one surface or object encounters when moving over another.

Front

What is the relationship between force and motion according to Newton's second law?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the effect of increasing the surface area on friction?

Back

Increasing the surface area generally does not significantly affect the amount of friction; it is more dependent on the nature of the surfaces in contact.

Front

What is the principle of magnetic poles?

Back

Like poles repel each other, while opposite poles attract.

Front

How does the type of surface affect the speed of a rolling object?

Back

Smoother surfaces reduce friction, allowing the object to roll faster, while rougher surfaces increase friction, slowing it down.
