Dynamics

Front

What does the law of inertia state?

Back

An object will continue moving at the same velocity or remain at rest unless acted upon by an outside force.

Front

What is the net force acting on an object?

Back

The vector sum of all forces acting on the object.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What kind of objects have inertia?

Back

All objects with mass.

Front

What are balanced forces?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Forces that are not equal and opposite, resulting in a change in motion.

Front

What is the SI unit for force?

Back

Newtons (N).

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, F = ma (Force equals mass times acceleration).

Front

What is gravitational force?

Back

The attractive force between two masses, proportional to their masses and inversely proportional to the square of the distance between them.
