Newtons laws

Front

What is Newton's 1st Law of Motion?

Back

An object at rest will remain at rest, and an object in motion will continue in motion at a constant velocity unless acted upon by an unbalanced force.

Front

What is Newton's 2nd Law of Motion?

Back

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

For every action, there is an equal and opposite reaction.

Front

Define inertia.

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the formula to calculate force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

What does the coefficient of friction represent?

Back

The coefficient of friction is a measure of how much frictional force exists between two surfaces in contact.

Front

What is static friction?

Back

Static friction is the frictional force that prevents two surfaces from sliding past each other when at rest.

Front

What is kinetic friction?

Back

Kinetic friction is the frictional force that opposes the motion of two surfaces sliding past each other.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will be harder to change its state of motion.
