newtons 1st and 3rd law

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. More massive objects have more inertia.

Front

What does Newton's First Law state?

Back

Newton's First Law states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by an unbalanced force.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to accelerate or decelerate, changing its state of motion.

Front

What is Newton's Third Law of Motion?

Back

Newton's Third Law states that for every action, there is an equal and opposite reaction.

Front

Give an example of Newton's Third Law in action.

Back

When a bird pushes down on a fence post, the fence post pushes back up on the bird with an equal force.

Front

What happens to an object at rest when no forces act on it?

Back

An object at rest will remain at rest unless acted upon by an unbalanced force.

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is a balanced force?

Back

A balanced force is when two forces acting on an object are equal in size and opposite in direction, resulting in no change in motion.

Front

How does friction affect motion?

Back

Friction is a force that opposes motion, causing objects to slow down or stop.

Front

What is an action-reaction force pair?

Back

An action-reaction force pair consists of two forces that are equal in size, opposite in direction, and act on different objects.
