speed, velocity, acceleration

Front

What is speed?

Back

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

Front

What is the formula for calculating average speed?

Back

Average speed = Total distance / Total time.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction, measured in meters per second (m/s).

Front

How does velocity differ from speed?

Back

Speed is a scalar quantity (only magnitude), 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, measured in meters per second squared (m/s²).

Front

What is the formula for calculating acceleration?

Back

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

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that cause an object to change its motion, resulting in acceleration.

Front

What are balanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is the unit of distance?

Back

The unit of distance is meters (m).

Front

If a car travels 100 km in 2 hours, what is its average speed?

Back

Average speed = 100 km / 2 h = 50 km/h.
