2024 Fall Semester Exam Review Part 1

Front

What does the term 'unbalanced forces' mean?

Back

Forces that cause a change in the motion of an object.

Front

What is the support force exerted upon an object in contact with another stable object?

Back

Normal Force.

Front

What is the term for the force applied to an object?

Back

Applied Force.

Front

In a vacuum, how does the weight of a 10-kg brick compare to a 1-kg book?

Back

The weight of the 10-kg brick is 10 times as much as the force on the 1-kg book, and it also has 10 times as much inertia.

Front

What is the formula to calculate the force of friction?

Back

Force of Friction = Coefficient of Friction x Normal Force.

Front

What is the coefficient of friction between tires and asphalt on wet roads?

Back

0.4.

Front

What is inertia?

Back

Inertia is the resistance of an object to any change in its state of motion.

Front

What is the weight force acting on an object?

Back

Weight force is the force due to gravity acting on an object, calculated as Weight = mass x gravity.

Front

What happens to the motion of an object when balanced forces act on it?

Back

The object remains at rest or continues to move at a constant velocity.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object's mass.
