Force & Motion Vocab

Front

Friction that occurs when one solid surface slides over another.

Back

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

Front

Equal forces acting on an object in opposite directions.

Back

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

Front

The force that one surface exerts on another when the two surfaces rub against each other.

Back

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

Front

The rate at which velocity changes.

Back

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

Front

Friction that occurs as an object moves through a liquid.

Back

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

Front

The tendency of an object to resist changes in its state of motion.

Back

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

Front

The force of attraction between two masses.

Back

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

Front

The product of an object's mass and its velocity.

Back

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

Front

The distance traveled per unit of time.

Back

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

Front

The change in position of an object over time.

Back

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