Speed and Acceleration

Front

What is motion?

Back

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

Front

What is speed?

Back

The distance traveled by a moving object per unit of time.

Front

How do you calculate average speed?

Back

Average speed = Total distance / Total time.

Front

What is acceleration?

Back

The rate of change of velocity of an object.

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 does it mean if an object is in motion?

Back

It means that the object's distance from another object is changing.

Front

If a car travels 300 km in 3 hours, what is its average speed?

Back

Average speed = 300 km / 3 hours = 100 km/h.

Front

What is the formula for acceleration?

Back

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

Front

What is a reference point?

Back

A stationary object used to determine the position of another object.

Front

What is the unit of speed?

Back

Common units include meters per second (m/s) and kilometers per hour (km/h).
