Unit 2 force and motion

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time

Front

Define gravitational force.

Back

Front

What is the unit of speed in the metric system?

Back

The unit of speed is meters per second (m/s).

Front

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

Back

Distance = Speed x Time

Front

What does a flat line on a distance-time graph indicate?

Back

A flat line indicates that the object is at rest and not moving.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

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 does it mean for an object to return to its reference point?

Back

It means the object has traveled back to its starting position, resulting in a displacement of zero.

Front

What is the significance of point B to point C in a distance-time graph?

Back

It indicates a period of time where the object is not moving, such as a stop.

How can you determine the total time taken for a journey from a distance-time graph?

Back

By measuring the total time elapsed from the start to the end of the journey on the graph.
