Newton's 2nd Law

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. It can be expressed with the formula F = ma.

Front

How do you calculate mass using Newton's 2nd Law?

Back

Mass can be calculated using the formula m = F/a, where F is the net force applied to the object and a is the acceleration.

Front

If a force of 250 N results in an acceleration of 5 m/s², what is the mass of the object?

Back

The mass of the object is 50 kg, calculated using m = F/a = 250 N / 5 m/s².

Front

What happens to the acceleration of an object if the force applied to it increases?

Back

The acceleration of the object increases, as acceleration is directly proportional to the net force applied.

Front

If two objects have the same force applied but different masses, which will have a greater acceleration?

Back

The object with the smaller mass will have a greater acceleration, as acceleration is inversely proportional to mass.

Front

What is the relationship between mass and force required to change an object's motion?

Back

The larger the mass of an object, the more force is needed to change its motion.

Front

If the net force on an object doubles, what happens to its acceleration?

Back

The acceleration also doubles, as acceleration is directly proportional to net force.

Front

What is the formula for calculating acceleration?

Back

Acceleration can be calculated using the formula a = F/m, where F is the net force and m is the mass.

Front

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

Back

The unit of force in the SI system is the Newton (N).

Front

What is the effect of increasing mass on acceleration when the same force is applied?

Back

Increasing mass will decrease the acceleration when the same force is applied, as acceleration is inversely proportional to mass.
