Newtons Laws

Front

What is Newton's 1st 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.

What is inertia in the context of Newton's 1st Law?

Back

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

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will be harder to change its state of motion.

Front

What is Newton's 2nd 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 (F = m x a).

Front

What does the equation F = m x a represent?

Back

It represents Newton's 2nd Law, where F is the net force, m is the mass, and a is the acceleration.

Front

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

Back

If the mass increases while the force remains constant, the acceleration decreases.

What is Newton's 3rd Law of Motion?

Back

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

Can you give an example of Newton's 3rd Law?

Back

When a balloon is released, the air pushes out in one direction, and the balloon moves in the opposite direction.

Front

What is the significance of action and reaction forces?

Back

Action and reaction forces are equal in magnitude and opposite in direction, and they act on different objects.

How does Newton's 1st Law apply to a penny in motion?

Back

The penny will continue moving in a straight line at a constant speed unless acted upon by an external force.
