8.6A Review Calculating Newtons Second Law

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 (Force = mass x acceleration).

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

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms (kg).

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity, measured in meters per second squared (m/s²).

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size and opposite in direction, resulting in a net force of zero, meaning the object remains at rest or moves at a constant speed.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and opposite, resulting in a net force that causes an object to accelerate.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, caused by the contact between two surfaces.

Front

How does mass affect acceleration?

Back

According to Newton's Second Law, as mass increases, acceleration decreases if the same force is applied. This means heavier objects require more force to accelerate.

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). More force results in more acceleration, while more mass results in less acceleration for the same force.

Front

What happens to a rolling ball when it stops?

Back

A rolling ball stops due to friction, which is the force that opposes its motion.
