Live Friction and Gravity

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

How does mass affect weight on different celestial bodies?

Back

Weight is the force of gravity acting on an object's mass. On the Moon, which has less mass than Earth, a person weighs less due to the weaker gravitational pull.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, occurring when two surfaces come into contact.

Front

What are the types of friction?

Back

The main types of friction are static friction (preventing motion), sliding friction (opposing motion), rolling friction (when an object rolls), and fluid friction (when an object moves through a fluid).

Front

What is static friction?

Back

Static friction is the force that keeps an object at rest and prevents it from starting to move.

Front

What is sliding friction?

Back

Sliding friction is the force that opposes the motion of an object sliding over a surface.

Front

What is rolling friction?

Back

Rolling friction is the force that opposes the motion of a rolling object, typically less than sliding friction.

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 formula for calculating weight?

Back

The formula for weight (W) is W = mg, where m is mass and g is the acceleration due to gravity.

What happens to a soccer ball when kicked?

Back

When a soccer ball is kicked, it rises to a certain height and then stops due to the effects of gravity and friction.
