Newtons First Law

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 is inertia?

Back

Inertia is the property of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia. This means that heavier objects require more force to change their motion.

Front

What is an applied force?

Back

An applied force is a force that is applied to an object by a person or another object.

Front

What is a normal force?

Back

The normal force is the support force exerted upon an object that is in contact with another stable object, typically acting perpendicular to the surface.

Front

What is net force?

Back

Net force is the vector sum of all the forces acting on an object. It determines the object's acceleration according to Newton's Second Law.

Front

What happens when the net force on an object is zero?

Back

When the net force on an object is zero, the object will maintain its current state of motion, either remaining at rest or moving at a constant velocity.

Front

What is the relationship between force and motion?

Back

Force is required to change the motion of an object. If no net force acts on an object, its motion will not change.

Front

Can an object have inertia if it is not moving?

Back

Yes, all objects with mass have inertia, regardless of whether they are moving or at rest.

Front

What is an example of an unbalanced force?

Back

An unbalanced force occurs when the forces acting on an object are not equal in size and opposite in direction, causing the object to accelerate.
