Speed, Velocity, and Acceleration Vocabulary

Front

What is speed?

Back

Speed is the distance traveled by an object in a given amount of time, usually expressed in units like meters per second (m/s) or kilometers per hour (km/h).

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction. It includes both the magnitude (how fast) and the direction of motion.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity. It can involve speeding up, slowing down, or changing direction.

Front

What is a force?

Back

A force is a push or pull exerted on an object that can cause it to move, stop, or change direction.

Front

What is Newton's First Law of Motion?

Back

Newton's First Law states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by a net external force.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that only measures how fast an object is moving, while velocity is a vector quantity that measures speed in a specific direction.

Front

What does it mean for an object to be in uniform motion?

Back

An object is in uniform motion when it moves at a constant speed in a straight line.

Front

What is deceleration?

Back

Deceleration is a type of acceleration that occurs when an object slows down.
