Newton's Three 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 an unbalanced force.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object depends on the mass of the object and the amount of force applied. It can be expressed with the formula F = ma (Force = mass x acceleration).

What is inertia?

Back

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

How does mass affect force according to Newton's Second Law?

Back

The greater the mass of an object, the more force is required to accelerate it.

What is the relationship between force, mass, and acceleration?

Back

Force is directly proportional to the product of mass and acceleration (F = ma).

What happens to your weight on the Moon compared to Earth?

Back

Your weight would be less on the Moon because the Moon has a weaker gravitational pull than Earth.

Why is a heavier hammer more effective for driving nails?

Back

A heavier hammer has more mass, which increases the force applied to the nail when swung.

What is an example of Newton's Third Law in action?

Back

When you jump off a small boat, you push the boat backward as you move forward.

What is the role of unbalanced forces in motion?

Back

Unbalanced forces cause an object to change its state of motion, either by accelerating, decelerating, or changing direction.
