Dynamics

Front

What is the formula to find the force of an object?

Back

F = ma (Force = mass × acceleration)

Front

What happens to the inertia of an object if the mass increases?

Back

The inertia of an object increases as its mass increases.

Front

What happens to your apparent weight in a downward accelerating elevator?

Back

Your apparent weight decreases relative to your actual weight.

Front

What kind of objects have inertia?

Back

All objects with mass have inertia.

Front

What does Newton's First Law state?

Back

An object at rest will stay at rest, and an object in motion will stay in motion at constant velocity unless acted upon by an unbalanced force.

Front

What is the formula for momentum?

Back

p = mv (momentum = mass × velocity)

Front

What does Newton's Second Law state?

Back

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

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object, calculated as W = mg (weight = mass × gravitational acceleration).

Front

What is an unbalanced force?

Back

An unbalanced force is a net force that causes an object to accelerate.

Front

What is inertia?

Back

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