Great Big AP Exam Review Flashcard

Front

What happens to a cart's acceleration if the force acting on it doubles?

Back

The cart's acceleration doubles.

Front

Speed is a __________ quantity and velocity is a __________ quantity.

Back

Speed is a scalar quantity and velocity is a vector quantity.

Front

Which car has the greatest acceleration magnitude? A car that starts from 0 m/s to 20 m/s in 4 seconds, speeds up from 20 m/s to 40 m/s in 3 seconds, slows down from 50 m/s to stop in 2 seconds, or starts from 0 m/s to 20 m/s in 5 seconds?

Back

The car that slows down from 50 m/s to stop in 2 seconds has the greatest acceleration magnitude.

Front

A blue car travels 1000 m north and then 1000 m south in 200 seconds. What is the car's average velocity for the trip?

Back

0 m/s.

Front

What equation should be used to find the acceleration of a car that travels 110 m with an initial speed of 29 m/s and final speed of 34 m/s?

Back

Front

Define acceleration.

Back

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

Front

What is the formula for calculating average velocity?

Back

Front

What is the difference between scalar and vector quantities?

Back

Scalar quantities have magnitude only, while vector quantities have both magnitude and direction.

Front

What does it mean for an object to be in uniform motion?

Back

An object is in uniform motion if it travels equal distances in equal intervals of time.

Front

What is the relationship between force and acceleration according to Newton's second law?

Back

According to Newton's second law, force is equal to mass times acceleration (F = ma).
