Speed, Velocity, and Acceleration

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down, also known as deceleration.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity.

Front

What is the formula for calculating momentum?

Back

Momentum = Mass × Velocity

Front

What does a horizontal line on a speed-time graph indicate?

Back

A horizontal line indicates that the object is moving at a constant speed.
