Speed and 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

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 acceleration?

Back

Acceleration is the rate at which an object's velocity changes over time. It can be positive (speeding up) or negative (slowing down).

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is constant speed?

Back

Constant speed means that an object is moving at the same speed throughout its motion, with no changes in velocity.

Front

What is negative acceleration?

Back

Negative acceleration, also known as deceleration, occurs when an object slows down, resulting in a decrease in its velocity.

Front

What is the formula for calculating acceleration?

Back

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

Front

What does it mean if an object has a velocity of 0?

Back

If an object has a velocity of 0, it means that it is at rest and not moving.

Front

What is an example of an object in motion with constant speed?

Back

A car traveling on a straight road at a steady speed of 60 km/h is an example of constant speed.

Front

What is the unit of acceleration?

Back

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