8.6C Applying Newton's Laws of Force and Motion

Front

What is Newton's Third Law of Motion?

Back

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

Front

Define inertia.

Back

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

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces cause an object to accelerate.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m x a).

Front

What does the Law of Inertia state?

Back

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

Front

What is the role of friction in motion?

Back

Friction is a force that opposes motion between two surfaces in contact.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia and resistance to changes in motion.

Front

What happens when two objects collide according to Newton's laws?

Back

The forces they exert on each other are equal in magnitude and opposite in direction.

Front

What is net force?

Back

Net force is the total force acting on an object after all the forces are combined.

Front

How do you calculate the mass of an object if you know the force and acceleration?

Back

Mass = Force / Acceleration.
