Newton's Second Law Flashcard

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

Front

What happens to the acceleration of an object if the net force acting on it increases?

Back

If the net force acting on an object increases, the acceleration of the object also increases, assuming the mass remains constant.

Front

What is the relationship between mass and acceleration according to Newton's Second Law?

Back

According to Newton's Second Law, acceleration is inversely related to mass. This means that as mass increases, acceleration decreases for a given net force.

Front

What is the net force acting on an object?

Back

The net force is the vector sum of all the forces acting on an object. It determines the object's acceleration according to Newton's Second Law.

Front

If two objects have the same mass, but one has a greater net force acting on it, what can be said about their accelerations?

Back

The object with the greater net force will have a greater acceleration than the object with the smaller net 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 the acceleration of an object change if its mass is doubled while the net force remains constant?

Back

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

Front

What is the effect of gravity on an object's mass?

Back

Gravity does not affect an object's mass; mass remains constant regardless of the object's location in a gravitational field.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object and is measured in kilograms (kg), while weight is the force exerted by gravity on that mass and is measured in Newtons (N). Weight can change depending on the gravitational field strength.

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 net force, and m is mass.
