Newton Laws

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 with the same speed and in the same direction unless acted upon by a net external force.

Front

How do you calculate net force when two forces are acting in the same direction?

Back

Add the magnitudes of the two forces together.

Front

What is the definition of balanced forces?

Back

Balanced forces are two or more forces acting on an object that cancel each other out, resulting in no change in motion.

Front

What is the formula for Newton's Second Law of Motion?

Back

F = ma, where F is the net force, m is the mass, and a is the acceleration.

Front

What happens to the acceleration of an object if the force applied is increased?

Back

The acceleration of the object increases.

Front

What is the net force acting on an object?

Back

The net force is the vector sum of all the forces acting on an object.

Front

What is an example of Newton's Third Law of Motion?

Back

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

Front

How do you determine the direction of net force?

Back

The direction of the net force is the same as the direction of the greater force when forces are unbalanced.

Front

What is inertia?

Back

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

Front

What is the significance of the mass of an object in relation to force and acceleration?

Back

The mass of an object determines how much it will accelerate in response to a given force; greater mass results in less acceleration for the same force.
