speed, velocity, acceleration

Front

What is speed?

Back

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

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 of an object over time.

Front

What is the formula for calculating acceleration?

Back

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

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

What does it mean if an object has a constant speed?

Back

It means the object is moving the same distance in equal intervals of time.

Front

What is the difference between positive and negative acceleration?

Back

Positive acceleration means an increase in speed, while negative acceleration (deceleration) means a decrease in speed.

Front

What is the relationship between speed, distance, and time?

Back

Distance = Speed x Time.
