Newton Laws of Motion

Front

What is inertia?

Back

Inertia is the property of an object to resist changes in its state of motion. All objects with mass have inertia.

Front

What is Newton's 1st Law of Motion?

Back

Newton's 1st Law states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's 3rd Law of Motion?

Back

Newton's 3rd Law states that for every action, there is an equal and opposite reaction.

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = mass (m) × acceleration (a).

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it requires more force to change its motion.

Front

What is the relationship between force and acceleration?

Back

According to Newton's 2nd Law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What happens when you push against a stationary object?

Back

When you push against a stationary object, the object exerts an equal and opposite force back on you, as described by Newton's 3rd Law.

Front

What is an example of Newton's 1st Law in everyday life?

Back

An example is when a car suddenly stops, and passengers lurch forward due to their inertia.

Front

What is the significance of the net force in motion?

Back

The net force determines the acceleration of an object; if the net force is zero, the object will not accelerate.
