Motion and Speed - Ch 2

Front

What is the law of inertia?

Back

An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is acceleration?

Back

The rate of change of velocity of an object over time.

Front

What is instantaneous speed?

Back

The rate of change in position at a given point in time.

Front

What is average speed?

Back

The total distance traveled divided by the total time taken.

Front

What is velocity?

Back

The speed of an object in a specific direction.

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

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

Back

An object at rest.

Front

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

Back

A high speed of the object.

Front

What does a downward slope on a distance-time graph represent?

Back

The object is returning to the starting point.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time Interval.
