Force, Mass, and Acceleration

Front

What is Newton's second law of motion?

Back

Newton's second 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 force?

Back

Force can be calculated using the formula F = ma, where F is force, m is mass, and a is acceleration.

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

If an object has a mass of 5 kg and is accelerating at 2 m/s², what is the force acting on it?

Back

The force acting on the object is 10 N (calculated using F = ma: F = 5 kg * 2 m/s²).

Front

What is the relationship between mass and acceleration when a constant force is applied?

Back

When a constant force is applied, an increase in mass results in a decrease in acceleration, and vice versa.

Front

What is the formula to calculate acceleration?

Back

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

Front

What is the mass of an object that experiences a force of 100 N and accelerates at 4 m/s²?

Back

The mass of the object is 25 kg (calculated using m = F/a: m = 100 N / 4 m/s²).

Front

What is the acceleration of a 10 kg object when a force of 50 N is applied?

Back

The acceleration of the object is 5 m/s² (calculated using a = F/m: a = 50 N / 10 kg).

Front

What is the effect of doubling the mass of an object on its acceleration if the force remains constant?

Back

Doubling the mass of an object will halve its acceleration if the force remains constant.

Front

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

Back

The unit of mass in the SI system is the kilogram (kg).
