FLASHCARD QUESTION

Front

What happens to an object in circular motion if the centripetal force is removed?

Back

The object will move in a straight line tangent to the circle at the point where the force was removed.

3.

FLASHCARD QUESTION

Front

What is terminal velocity?

Back

The constant speed that a freely falling object eventually reaches when the resistance of the medium prevents further acceleration.

4.

FLASHCARD QUESTION

Front

How does gravitational force change with distance?

Back

The gravitational force decreases with the square of the distance between the centers of two objects.

5.

FLASHCARD QUESTION

Front

What is the formula for net force (F_net)?

Back

F_net = Fa - Ff, where Fa is the applied force and Ff is the frictional force.

6.

FLASHCARD QUESTION

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as weight = mass × gravitational acceleration (W = mg).

7.

FLASHCARD QUESTION

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.
