Intro to Motion Review

Front

What happens to acceleration when you slow down on a bicycle?

Back

Acceleration must be opposite the direction of motion.

Front

What is the measure of the change in velocity during a period of time?

Back

Acceleration.

Front

What is the term for the constant speed reached by free-falling objects when drag cancels acceleration?

Back

Terminal velocity.

Front

If a man walks 3 km north and then 4 km east, what is the total distance he walked?

Back

7 km.

Front

What conditions must be met to achieve constant velocity?

Back

Constant speed and direction.

Front

Define acceleration in the context of motion.

Back

Acceleration is the rate of change of velocity over 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 is the formula for calculating acceleration?

Back

Acceleration = (Final velocity - Initial velocity) / Time.

Front

What is drag in the context of motion?

Back

Drag is the resistance force that opposes the motion of an object through a fluid (like air or water).

Front

What is the significance of terminal velocity in free fall?

Back

Terminal velocity is the maximum velocity an object reaches when the force of drag equals the force of gravity, resulting in no further acceleration.
