Friction and gravity

Front

What is static friction?

Back

Static friction is the force that keeps an object at rest and prevents it from moving when a force is applied.

Front

What is friction?

Back

Friction is the force that two surfaces exert on each other as they rub against each other.

Front

What are the two factors that affect gravity?

Back

The two factors that affect gravity are mass and distance.

Front

What causes a soccer ball to stop after being kicked?

Back

The soccer ball stops due to friction acting against its motion.

Front

What is sliding friction?

Back

Sliding friction is the force that opposes the motion of two surfaces sliding past each other.

Front

What is rolling friction?

Back

Rolling friction is the force that opposes the motion of an object rolling over a surface.

Front

What is fluid friction?

Back

Fluid friction is the resistance encountered by an object moving through a fluid (liquid or gas).

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

How does distance affect gravity?

Back

As the distance between two objects increases, the gravitational force between them decreases.

Front

What is the role of gravity in everyday life?

Back

Gravity pulls objects towards the Earth, keeping us grounded and affecting how we move.
