Speed, Velocity, Acceleration V2

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 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

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken. Formula: Average Speed = Total Distance / Total Time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (only magnitude), while velocity is a vector quantity (magnitude and direction).

Front

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

Back

Average Speed = Total Distance / Total Time = 100 km / 2 hr = 50 km/h.

Front

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

Back

An object with constant velocity is moving at a steady speed in a straight line without changing direction.

Front

What is the formula for acceleration?

Back

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

Front

If a cyclist increases their speed from 10 m/s to 15 m/s in 5 seconds, what is their acceleration?

Back

Acceleration = (15 m/s - 10 m/s) / 5 s = 1 m/s².

Front

What is a vector quantity?

Back

A vector quantity is a physical quantity that has both magnitude and direction, such as velocity and acceleration.
