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

Front

How do you calculate force?

Back

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

Front

What happens to acceleration if the mass of an object is doubled while the force remains constant?

Back

If the mass of an object is doubled while the force remains constant, the acceleration is halved.

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 a net force of 10 N is applied to an object and it accelerates at 4 m/s², what is the mass of the object?

Back

The mass of the object is 2.5 kg, calculated using the formula m = F/a.

Front

What is the relationship between force, mass, and acceleration?

Back

The relationship is defined by Newton's Second Law: Force equals mass times acceleration (F = ma).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

What is the formula for calculating acceleration?

Back

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

Front

What is the effect of increasing force on acceleration?

Back

Increasing the force applied to an object will increase its acceleration, assuming the mass remains constant.

Front

What is the effect of increasing mass on acceleration?

Back

Increasing the mass of an object will decrease its acceleration if the force applied remains constant.
