Speed, Velocity, and 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/hr).

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction. It is a vector quantity, meaning it has both magnitude and direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time. It can be positive (speeding up) or negative (slowing down).

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the formula for calculating acceleration?

Back

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

Front

What is a unit of time?

Back

A unit of time is a measurement used to quantify the duration of events, commonly measured in seconds (sec), minutes (min), or hours (hr).

Front

What is a unit of speed?

Back

A unit of speed is a measurement of how fast an object is moving, commonly expressed in meters per second (m/s) or kilometers per hour (km/hr).

Front

If a car travels 150 km in 3 hours, what is its speed?

Back

Speed = Distance / Time = 150 km / 3 hr = 50 km/hr.

Front

How do you calculate distance using speed and time?

Back

Distance = Speed x Time.

Front

If a runner accelerates from 5 m/s to 15 m/s in 5 seconds, what is their acceleration?

Back

Acceleration = (15 m/s - 5 m/s) / 5 s = 2 m/s².
