Speed, Velocity, 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/h).

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 acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be positive (speeding up), negative (slowing down), or involve a change in direction.

Front

When does an object accelerate?

Back

An object accelerates when it changes its speed, direction, or both.

Front

What is the formula for calculating acceleration?

Back

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

Front

What is uniform acceleration?

Back

Uniform acceleration occurs when an object's velocity changes at a constant rate.

Front

What is the equation to calculate distance?

Back

Distance = Speed x Time.

Front

How do you calculate average speed?

Back

Average Speed = Total Distance / Total Time.

Front

What is instantaneous speed?

Back

Instantaneous speed is the speed of an object at a specific moment in time.

Front

What is the unit of acceleration?

Back

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