Speed, Velocity, Acceleration

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can involve speeding up, slowing down, or changing direction.

Front

What is the formula for calculating acceleration?

Back

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

Front

What is speed?

Back

Speed is the distance traveled per unit of time, regardless of direction.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

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

What two factors does speed depend on?

Back

Speed depends on distance and time.

Front

What two factors does velocity depend on?

Back

Velocity depends on speed and direction.

Front

What is uniform acceleration?

Back

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

Front

What is the unit of acceleration?

Back

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

Front

What is the difference between positive and negative acceleration?

Back

Positive acceleration means an increase in speed, while negative acceleration (deceleration) means a decrease in speed.
