Front

What is the net force acting on an object in equilibrium?

Back

zero

Front

In a free body diagram, what do arrows represent?

Back

Forces

Front

What is the formula for Newton's second law of motion?

Back

F = ma

Front

What is the other name for Newton's third law of motion?

Back

law of action and reaction

Front

What is a free body diagram?

Back

A free body diagram is a visual representation of the forces acting on an object.

Front

What does Newton's first law of motion state?

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 is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How do you calculate net force?

Back

Net force is calculated by vector addition of all individual forces acting on an object.

Front

What is the significance of the direction of arrows in a free body diagram?

Back

The direction of arrows indicates the direction of the forces acting on the object.

Front

What is the relationship between mass and acceleration in Newton's second law?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
