Friction and Gravity

Front

What is weight?

Back

Weight is the measure of gravitational force acting on an object.

Front

What type of friction do skateboard wheels experience when moving?

Back

Rolling Friction.

Front

Do astronauts float away on the moon?

Back

No, because the Moon's gravity pulls them down.

Front

How do you calculate net force when forces are acting in opposite directions?

Back

You subtract the forces.

Front

Do forces have strength and direction?

Back

True.

Front

What is gravity?

Back

Gravity is the force that attracts two bodies towards each other.

Front

What is static friction?

Back

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

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 fluid friction?

Back

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

Front

What happens to weight as you move further from the Earth's surface?

Back

Weight decreases as you move further from the Earth's surface due to reduced gravitational pull.
