Newton's Laws of Motion

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

Which has more inertia: a bowling ball or a tennis ball?

Back

A bowling ball has more inertia than a tennis ball because it has greater mass.

Front

What does Newton's First Law state?

Back

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

Front

What is the relationship between force and acceleration?

Back

The greater the force applied to an object, the greater the acceleration of that object, according to Newton's Second Law.

Front

Which has less inertia: a feather or a hammer?

Back

A feather has less inertia than a hammer because it has less mass.

Front

What happens to acceleration when less force is applied?

Back

The lesser the force that is applied, the lesser the acceleration of the object.

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).

Front

Define mass in the context of Newton's Laws.

Back

Mass is a measure of the amount of matter in an object and is a measure of its inertia.

Front

What is the formula for calculating force?

Back

Force can be calculated using the formula F = ma, where F is force, m is mass, and a is acceleration.

Front

How does mass affect acceleration?

Back

For a given force, an increase in mass will result in a decrease in acceleration.
