Newtons Laws

Front

What is Newton's First Law?

Back

An object at rest stays at rest, and an object in motion stays in motion 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

What does F=ma represent?

Back

F=ma is Newton's Second Law, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration.

Front

What is Newton's Second Law?

Back

Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is Newton's Third Law?

Back

Newton's Third Law states that for every action, there is an equal and opposite reaction.

Front

If a 20 kg bike accelerates at 10 m/s², what is the force applied?

Back

200 Newtons (calculated using F=ma).

Front

What happens when forces are balanced?

Back

When forces are balanced, the object remains at rest or continues to move at a constant velocity.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the object will accelerate in the direction of the larger force.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass cannot be created or destroyed in a closed system.

Front

What is an example of Newton's First Law in everyday life?

Back

A passenger lurches forward in a car when it suddenly stops, demonstrating inertia.
