Forces, Friction & Gravity

Front

What is a force?

Back

A force is a push or pull with a specific magnitude and direction.

Front

What type of friction occurs when two surfaces slip past each other?

Back

Sliding friction.

Front

In the presence of unbalanced forces, in which direction will an object move?

Back

An object will move in the direction of the larger force.

Front

What are unbalanced forces?

Back

Forces that have a net force of some value, affecting the object's movement.

Front

What type of fluid friction acts on an object moving through the air?

Back

Air resistance.

Front

What is the definition of gravity?

Back

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

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 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

What is the formula for calculating weight?

Back

Weight = mass × acceleration due to gravity (W = mg).

Front

What is kinetic friction?

Back

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