NEWTON'S 1ST LAW-2

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.

Front

What is inertia?

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 a balanced force?

Back

Balanced forces are forces acting on an object that combine to produce a net force of zero, resulting in no change in motion.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that results in a net force greater than zero, causing a change in the object's motion.

Front

What happens to a moving object when no net force acts on it?

Back

It continues to move at a constant velocity.

Front

What is net force?

Back

Net force is the vector sum of all the forces acting on an object.

Front

If two forces of 20 N and 25 N act in the same direction, what is the net force?

Back

The net force is 45 N in the direction of the applied forces.

Front

What is the effect of applying more force to an object?

Back

Applying more force to an object will increase its acceleration.

Front

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

Back

According to Newton's 2nd Law, force equals mass times acceleration (F = ma).
