Newton's Second Law

Front

What does Newton's Second Law state?

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. This is often expressed with the formula F=MA.

Front

What is the formula for calculating force according to Newton's Second Law?

Back

The formula for calculating force is F = MA, where F is force, M is mass, and A is acceleration.

Front

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

Back

The relationship is that force equals mass times acceleration (F=MA). This means that for a given mass, an increase in force will result in an increase in acceleration.

Front

What is meant by unbalanced forces?

Back

Unbalanced forces are forces that do not cancel each other out, resulting in a net force that causes an object to accelerate in the direction of the net force.

Front

What happens to an object at rest when unbalanced forces act on it?

Back

When unbalanced forces act on an object at rest, the object begins to move in the direction of the net force.

Front

If two objects have the same force applied to them, how does their mass affect their acceleration?

Back

If two objects have the same force applied, the object with the smaller mass will experience greater acceleration, while the object with the larger mass will experience less 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

How do you calculate the force required to accelerate an object?

Back

To calculate the force required to accelerate an object, use the formula F = MA, where M is the mass of the object and A is the desired acceleration.

Front

What is the effect of increasing the mass of an object on its acceleration if the same force is applied?

Back

Increasing the mass of an object will decrease its acceleration if the same force is applied, according to the formula F = MA.

Front

What is the significance of the net force in Newton's Second Law?

Back

The net force is the total force acting on an object after all the forces are combined. It determines the object's acceleration according to Newton's Second Law.
