Speed and Acceleration

Front

What is a place or object used for comparison to determine if something is in motion?

Back

A reference point.

Front

True or False: Motion is measured relative to a reference point.

Back

True.

Front

What is speed that does not change called?

Back

Constant speed.

Front

What is the rate at which velocity changes called?

Back

Acceleration.

Front

If a car traveled 300 km in 3 hours, what can you find?

Back

Average speed.

Front

What is the formula for calculating average speed?

Back

Average Speed = Total Distance / Total Time.

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 unit is commonly used to measure speed?

Back

Kilometers per hour (km/h) or meters per second (m/s).

Front

What does acceleration indicate about an object's motion?

Back

It indicates a change in the object's velocity over time.

Front

What is the formula for acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.
