- Newton's 1st Law
- Newton's 2nd Law
- Newton's 3rd Law
- Objects in motion stay in motion and objects at rest stay at rest (unless acted upon by a resultant force)
- F = MA (resultant force = mass x acceleration
- Every action has an equal and opposite reaction
If an object is moving in a circular path – what is happening to its velocity?CorrectIncorrect
If a car is moving but the forces are balanced – what will happen to the speed of the car?CorrectIncorrect
Using the equation F = MA – calculate the force of a ball with a mass of 15kg that is accelerated at 2m/s²?CorrectIncorrect
In an equilibrium situation – the forces between two objects are?CorrectIncorrect
Which of the following equations is the correct way to make A the subject of the equation F = MA?CorrectIncorrect
What is a resultant force?CorrectIncorrect
For circular motion to take place there must be a resultant force that acts towards the centre of the circle. What is the name of this force?CorrectIncorrect
If a car experiences a resultant force in the forwards direction, what will happen to the motion of the car?CorrectIncorrect
Complete the sentence: Newton’s Second Law defines inertial mass. Inertial mass is a measure of how difficult it is to change the of an object.

What are Newton’s Laws of Motion?
Newton’s Laws of Motion were devised by the legendary physicist, mathematician and philosopher Issac Newton who lived during the 17th century. He was renowned for being a recluse and spent many years living alone, thinking and experimenting. He invented the field of calculus and many other great achievements including his laws of motion.
The laws describe the motion of objects through space and were successfully applied to the motion of the planets until the succession of these laws by General Relativity, an invention of Albert Einstein. Newton’s Laws partly due to their simplicity are still in use today.
What is Newton’s 1st Law?
Newton’s 1st Law of Motion describes the tendency of objects to continue their motion unless acted upon by an external force. If an object is in motion at any speed, it will continue at that speed. Similarly, objects at rest will stay at rest. Of course, gravitational influence conceals this law on Earth and this is counter to our experience.
What is Newton’s 2nd Law?
Newton’s 2nd Law of Motion describes the relationship between the strength of a force, the mass of an object and its acceleration. The equation is as follows:
F = MA
where F is force, M is mass and A is acceleration.
Forces are vector quantities with both magnitude and direction.
What is Newton’s 3rd Law?
Newton’s 3rd Law of Motion describes the opposing forces which exist for any object or action-reaction forces. As you read this you are likely sat down and so the force of your weight on the chair is exactly counteracted by the force of the chair on your behind.
