Newtons 2nd Law

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 a net external force.

Front

What is the formula for Newton's Second Law?

Back

F = ma, where F is the net force, m is the mass, and a is the acceleration.

How does acceleration relate to net force according to Newton's Second Law?

Back

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

If a car has a mass of 2500 kg and a net force of 5000 N, what is its acceleration?

Back

The acceleration is 2 m/s².

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 term 'net force' mean?

Back

Net force is the vector sum of all the forces acting on an object.

What happens to the acceleration of an object if the mass increases while the net force remains constant?

Back

The acceleration decreases.

Front

What is the relationship between mass and acceleration in Newton's Second Law?

Back

Mass and acceleration are inversely related when the net force is constant.

Front

What is inertia in the context of Newton's First Law?

Back

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