Speed and Acceleration

Front

What is speed?

Back

Speed is the distance traveled by a moving object per unit of time.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity.

Front

What does it mean when an object is in motion?

Back

An object is in motion when its distance from another object is changing.

Front

How is speed calculated?

Back

Speed equals distance divided by time.

Front

What is a reference point in motion?

Back

A reference point is a stationary object used to determine if another object is in motion.

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 happens to the speed of an object in free fall?

Back

The speed of an object in free fall increases due to the acceleration of gravity.

Front

What is uniform motion?

Back

Uniform motion occurs when an object travels equal distances in equal intervals of time.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (final velocity - initial velocity) / time.

Front

What is the unit of speed?

Back

The unit of speed is typically meters per second (m/s).
