Motion and Forces Vocab Flashcard Review

Front

What is motion?

Back

A change in an object’s position relative to a reference point.

Front

What does the Law of Conservation of Momentum state?

Back

If no external forces act on a group of objects, their total momentum does not change.

Front

What is displacement?

Back

Distance and direction of an object’s change in position from the starting point.

Front

What is momentum?

Back

Property of a moving object that equals its mass times its velocity.

Front

What does the first law of motion state?

Back

An object moving at a constant velocity keeps moving at that velocity unless an unbalanced force acts on it.

Front

What is speed?

Back

The distance traveled per unit of time.

Front

What is velocity?

Back

The speed of an object in a specific direction.

Front

What is acceleration?

Back

The rate of change of velocity of an object.

Front

What is force?

Back

A push or pull on an object resulting from the object's interaction with another object.

Front

What is the second law of motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
