Newton's 2nd Law

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law states that the force acting on an object is equal to the mass of that object multiplied by its acceleration (F = m × a).

Front

What is the formula to calculate force?

Back

The formula to calculate force is F = m × a, where F is force, m is mass, and a is acceleration.

Front

If a car has a mass of 1,000 kg and accelerates at 3 m/s², what is the force?

Back

3,000 N

Front

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

Back

The unit of force is the Newton (N).

Front

How does increasing mass affect force if acceleration is constant?

Back

If mass increases while acceleration remains constant, the force must also increase.

Front

How does increasing acceleration affect force if mass is constant?

Back

If acceleration increases while mass remains constant, the force must also increase.

Front

What is the net force when two forces act in opposite directions?

Back

The net force is the difference between the two forces, taking direction into account.

Front

If Barsoum’s room pulls with 45 N to the left and Coach Camacho's room pulls with 50 N to the right, what is the net force?

Back

5N to the right. Coach Camacho's Class won.

Front

What happens to an object at rest when a net force is applied?

Back

An object at rest will accelerate in the direction of the net force applied.

Front

What is inertia?

Back

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