Newton's Laws of Motion

Front

If an object is in motion it will remain ______, unless an external force acts on it.

Back

in motion (This is a statement of Newton's First Law of Motion, also known as the Law of Inertia.)

Front

The velocity of an object changes only when it is acted on by an _________ force.

Back

unbalanced (An unbalanced force causes a change in the motion of an object.)

Front

A change in velocity is called __________.

Back

acceleration (Acceleration is the rate of change of velocity of an object.)

Front

Objects with larger _____ also have greater inertia.

Back

mass (Inertia is the resistance of an object to any change in its state of motion.)

Front

Combination of all the forces acting on an object is called ______?

Back

net force (Net force is the vector sum of all the forces acting on an object.)

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.

Front

What is Newton's Second Law of Motion?

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 Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is inertia?

Back

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

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).
