Newtons Laws of Motion!

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

What does it mean for forces to be balanced?

Back

When the net force acting on an object is zero, meaning all forces are equal in size and opposite in direction.

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) x acceleration (a) or F = m x a.

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.

What is an example of an unbalanced force?

Back

A soccer ball being kicked; the force of the kick is greater than the opposing forces, causing the ball to accelerate.

What is Newton's Third Law of Motion?

Back

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

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the law of universal gravitation?

Back

Every point mass attracts every other point mass in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

What is a wedge in terms of simple machines?

Back

A wedge is a simple machine that can be used to split things apart or hold objects open, like a door.

Front

What happens to an object at rest when no net force acts on it?

Back

It remains at rest.
