Newton's Second Law Review

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 does mass affect acceleration when a constant force is applied?

Back

When a constant force is applied, an increase in mass results in a decrease in acceleration. Conversely, a decrease in mass results in an increase in acceleration.

Front

What happens to acceleration if the force applied is doubled?

Back

If the force applied to an object is doubled, the acceleration of the object also doubles, assuming mass remains constant.

Front

What is the formula to calculate force?

Back

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

Front

Define inertia in the context of Newton's laws.

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

If the mass of an object is halved, what happens to its acceleration when the same force is applied?

Back

If the mass of an object is halved, its acceleration will double when the same force is applied.

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). This means that for a given mass, an increase in force results in an increase in acceleration.

Front

What is the effect of friction on motion according to Newton's laws?

Back

Friction opposes the motion of an object, reducing its acceleration. It acts in the opposite direction to the applied force.

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

How does acceleration change if both mass and force are doubled?

Back

If both mass and force are doubled, the acceleration remains the same because the increase in force is offset by the increase in mass.
