Newton's First Law (Law of Inertia) | GCSE Physics
Newton's First Law describes how objects behave when the forces acting on them are balanced.
What is the resultant force on a car at constant velocity?
What is Newton's First Law (Law of Inertia) | GCSE Physics?
"The law stating that an object will remain at rest or move at a constant velocity unless acted upon by a resultant force."
What is the resultant force on an object if a 10N force acts right and a 4N force acts left?
Which of these is the correct vector equivalent of 'Distance'?
An object moves at a constant velocity. What is the resultant force?
What is the unit of the spring constant (k)?
Balanced Forces
Balanced forces result in zero acceleration.
Stationary objects remain stationary.
Moving objects continue at a constant velocity (constant speed + direction).
Forces cannot change motion unless there is a resultant force.
Exam Trap: Students often say "the object stops" when forces are balanced. It doesn't! It just stops ACCELERATING.

The fastest way to improve your grade is to practise exam-style questions, identify your gaps, and focus only on what you don't know.
