Honors Forces Test Review

Front

An object falling through the air at terminal speed experiences _____?

Back

A net force of 0, balanced forces, no acceleration, all of the above.

Front

Every action has a(n) ____ and ____ reaction. Which law of motion is this?

Back

Equal, opposite; third law of motion.

Front

An object’s tendency to resist change in motion is a measure of____?

Back

Inertia.

Front

What is the normal force acting on a 67kg box resting on a flat surface with a 150N force applied at 30° above the horizontal?

Back

595 N.

Front

What is the friction force acting on a 67kg box resting on a flat surface with a 150N force applied at 30° above the horizontal?

Back

179 N.

Front

Define terminal velocity.

Back

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

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What does the coefficient of friction represent?

Back

The ratio that represents the frictional force between two bodies in contact to the normal force pressing them together.

Front

Explain the concept of balanced forces.

Back

Balanced forces occur when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What is the formula for calculating frictional force?

Back

Frictional Force = Coefficient of Friction × Normal Force.
