FLASHCARD QUESTION

Front

What is the normal force?

Back

The normal force is the force exerted by a surface that supports the weight of an object resting on it, acting perpendicular to the surface.

2.

FLASHCARD QUESTION

Front

What does the coefficient of static friction indicate?

Back

The coefficient of static friction indicates how easily an object will slide across a surface when at rest.

3.

FLASHCARD QUESTION

Front

What type of friction prevents a stationary object from moving?

Back

Static friction prevents a stationary object from moving when a force is applied.

4.

FLASHCARD QUESTION

Front

What are the units of force in the International System of Units (SI)?

Back

The units of force in the SI system are newtons (N).

5.

FLASHCARD QUESTION

Front

What does it mean if an object is moving at a constant speed?

Back

If an object is moving at a constant speed, the net force acting on it is zero, meaning all forces are balanced.

6.

FLASHCARD QUESTION

Front

What is Newton's First Law of Motion?

Back

Newton's First Law states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

7.

FLASHCARD QUESTION

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).
