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

The distance an object travels per unit of time.

Back

Speed is the measure of how fast an object is moving, calculated as distance divided by time.

Front

The tendency of an object to resist any change in its 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 product of an object's mass and velocity.

Back

Momentum is a vector quantity defined as the product of an object's mass and its velocity.

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 (liquid or gas).

Front

The force that attracts two bodies toward each other, proportional to their masses and inversely proportional to the square of the distance between them.

Back

Gravity is the force that pulls objects toward each other, most notably the attraction between the Earth and objects on it.

Front

The rate of change of velocity of an object.

Back

Acceleration is the change in velocity per unit of time, indicating how quickly an object is speeding up or slowing down.

Front

The force that opposes the motion of an object in contact with a surface.

Back

Friction is the resistance that one surface or object encounters when moving over another.

Front

The speed of an object in a specific direction.

Back

Velocity is a vector quantity that refers to the rate at which an object changes its position.

Front

The change in position of an object over time.

Back

Displacement is the vector quantity that refers to the change in position of an object from its initial point to its final point.
