TMS 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/h).

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction, e.g., 40 km/h north.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, measured in meters per second squared (m/s²).

Front

What does it mean if an object has a negative acceleration?

Back

A negative acceleration indicates that the object is slowing down.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = (Final Velocity (v) - Initial Velocity (u)) / Time (t).

Front

What is the difference between speed and velocity?

Back

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

Front

Can an object be moving at a constant speed but still be accelerating?

Back

Yes, if the object is changing direction, it is accelerating even if its speed is constant.

Front

What is uniform acceleration?

Back

Uniform acceleration occurs when an object's acceleration is constant over time.

Front

What is the unit of acceleration?

Back

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

Front

If a car is moving at 60 km/h and then speeds up to 80 km/h, what is happening to its velocity?

Back

The car's velocity is increasing, indicating positive acceleration.
