Speed and Motion

Front

What is speed?

Back

Speed is the distance traveled per unit of time, usually measured in meters per second (m/s) or kilometers per hour (km/h).

Front

What is motion?

Back

Motion is the change in position of an object over time.

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 negative acceleration?

Back

Negative acceleration, also known as deceleration, occurs when an object is slowing down.

Front

What does it mean when a car is moving towards the starting point?

Back

It means the car is reversing or coming back to its original position.

Front

What is a graph of motion?

Back

A graph of motion visually represents the relationship between distance and time, showing how an object's position changes over time.

Front

What is constant speed?

Back

Constant speed means an object is moving at the same speed throughout its motion.

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

How do you calculate total time traveled?

Back

Total time traveled can be calculated by adding the time intervals of each segment of motion.

Front

What does it mean if a runner stops for a rest?

Back

It means the runner is not moving and has paused their motion.
