Speed, Velocity, Acceleration Introduction

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

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

Velocity is speed with a direction. While speed is a scalar quantity (only magnitude), 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. It can be positive (speeding up) or negative (slowing down).

Front

How do you calculate acceleration?

Back

Acceleration is calculated by dividing the change in velocity by the time taken for that change. Formula: Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is constant velocity?

Back

Constant velocity means an object is moving at a steady speed in a straight line without changing direction.

Front

What is the formula for distance?

Back

Distance can be calculated using the formula: Distance = Speed x Time.

Front

If a car travels at a speed of 60 km/h for 2 hours, how far does it travel?

Back

Distance = Speed x Time = 60 km/h x 2 h = 120 km.

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 is accelerating?

Back

If an object is accelerating, it means its velocity is changing over time, either increasing or decreasing.
