newtons laws

Front

What does Newton's third law state about action and reaction?

Back

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

Front

What is the first law of motion?

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 a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What unit is used to measure force?

Back

Newtons (N) are used to measure force.

Front

What is the net force if two forces of 3 N and 3 N act in the same direction?

Back

The net force is 6 N.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the total forces acting on an object are not equal, causing the object to accelerate.

Front

How does mass affect the force required to move an object?

Back

The greater the mass of an object, the greater the force required to accelerate it.

Front

What is inertia?

Back

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

Front

What is the formula for calculating force?

Back

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

Front

What is the relationship between force, mass, and acceleration according to Newton's second law?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
