Force & Motion Vocab

Sliding friction is the resistance that occurs when two solid surfaces slide against each other.

Balanced forces are forces that are equal in size but opposite in direction, resulting in no change in motion.

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Acceleration is the change in velocity of an object over time.

Fluid friction is the resistance encountered by an object moving through a fluid, such as water or air.

Inertia is the property of matter that causes it to remain at rest or in uniform motion unless acted upon by an external force.

Gravity is the force that pulls objects toward each other, depending on their masses and the distance between them.

Momentum is a measure of the motion of an object, calculated as the product of its mass and velocity.

Speed is the rate at which an object covers distance, typically measured in meters per second (m/s).

Motion refers to the change in an object's position relative to a reference point.
