Newton's Laws of Motion

Front

What is a balanced force?

Back

A balanced force is a force pair that has a net force of zero, meaning that the forces acting on an object are equal in size and opposite in direction, resulting in no change in motion.

Front

What is Newton's First Law known as?

Back

Newton's First Law is known as the Law of Inertia, which states that an object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by a net external force.

Front

What is the net force if two equal forces of 5 N are acting in opposite directions?

Back

The net force is 0 N, as the forces cancel each other out.

Front

What is the formula for Newton's Second Law of Motion?

Back

The formula for Newton's Second Law of Motion is F = ma, where F is the net force, m is the mass, and a is the acceleration.

Front

Why is it harder to push a van filled with bowling balls than a van filled with basketballs?

Back

It is harder to push the van filled with bowling balls because the mass of the bowling balls is greater than the mass of the basketballs, resulting in greater inertia.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. The greater the mass of an object, the greater its inertia.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that results in a net force greater than zero, causing an object to accelerate in the direction of the net force.

Front

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

Back

According to Newton's Second Law, as mass increases, acceleration decreases for a given net force. This means heavier objects require more force to accelerate.

Front

What happens to an object in motion if no net force acts on it?

Back

If no net force acts on an object in motion, it will continue to move at a constant velocity in a straight line.

Front

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

Back

The relationship is described by Newton's Second Law: F = ma, indicating that force is the product of mass and acceleration.
