Front

What is the definition of speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

Front

What happens to the speed of an object in free fall?

Back

The speed of an object in free fall increases at a constant rate due to the acceleration of gravity.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What does a steeper slope on a distance-time graph indicate?

Back

A steeper slope indicates a higher speed of the object.

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 per unit of time, measured in meters per second squared (m/s²).

Front

What is the effect of air resistance on a falling object?

Back

Air resistance opposes the motion of a falling object, reducing its acceleration and terminal velocity.

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed that a freely falling object eventually reaches when the resistance of the medium prevents further acceleration.

Front

How does mass affect the acceleration of an object?

Back

According to Newton's second law, acceleration is inversely proportional to mass; as mass increases, acceleration decreases for a given force.

Front

What is the relationship between distance, speed, and time?

Back

Distance is equal to speed multiplied by time (Distance = Speed x Time).
