Speed, Velocity, Acceleration Review

Front

What is acceleration?

Back

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

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time

Front

What is the unit of acceleration?

Back

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

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

How do you calculate speed?

Back

Speed = Distance / Time

Front

What happens to acceleration when an object slows down?

Back

When an object slows down, it is still accelerating, but it is experiencing negative acceleration (deceleration).

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

If a car travels 100 meters in 5 seconds, what is its speed?

Back

Speed = 100 meters / 5 seconds = 20 m/s.

Front

What is the equation to calculate time?

Back

Time = Distance / Speed
