Standard 9 review - Speed and motion

Front

What is the formula to find the speed of an object?

Back

Speed = Distance / Time

Front

What does a graph showing a straight line indicate about an object's motion?

Back

The object is moving at a constant speed.

Front

At what time and distance do two objects meet if they are at the same position?

Back

They meet at 40 seconds and 90 meters.

Front

What does it mean if a car is moving away from the starting point?

Back

The car's position is increasing relative to the starting point.

Front

How can you determine which runner had a head start in a race?

Back

The runner who reaches a certain point first without having started at the same time has a head start.

Front

What is the definition of speed in physics?

Back

Speed is the distance traveled per unit of time.

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

How do you calculate the distance traveled if you know speed and time?

Back

Distance = Speed x Time

Front

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

Back

A steeper slope indicates a higher speed.

Front

What is the significance of the y-axis on a distance-time graph?

Back

The y-axis represents the distance traveled by the object.
