Newton's First Law and Forces Flashcard

Front

What is mass?

Back

Mass is the quantity of matter contained in an object, and it depends on the number and types of atoms in the object.

Front

What is Newton's First Law of Motion?

Back

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

Front

What is inertia?

Back

Inertia is an object’s tendency to remain at rest or, if moving, to remain in motion.

Front

What is a free-body diagram?

Back

A free-body diagram is a graphical representation used to visualize the forces acting on an object.

Front

What types of forces can be represented in a free-body diagram?

Back

Only external forces can be represented in a free-body diagram.

Front

What is friction?

Back

Friction is a force that opposes the relative motion of two surfaces in contact.

Front

How does friction affect motion?

Back

Friction causes an object in motion to slow down and eventually stop.

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it is more resistant to changes in its state of motion.

Front

How do you represent two perpendicular forces in a free-body diagram?

Back

The two force arrows will be drawn at a right angle to one another.

Front

What is the net force?

Back

The net force is the vector sum of all the forces acting on an object.
