2nd Law of Motion

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This can be expressed with the formula: F = ma (Force = mass x acceleration).

Front

What is the formula to calculate acceleration?

Back

Acceleration can be calculated using the formula: a = F/m (acceleration = force/mass).

Front

What does it mean for forces to be balanced?

Back

Forces are balanced when the net force acting on an object is zero, resulting in no change in motion.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the net force acting on an object is not zero, causing the object to accelerate in the direction of the net force.

Front

How does mass affect acceleration?

Back

The greater the mass of an object, the less acceleration it will have for a given force. This is because acceleration is inversely proportional to mass.

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 centripetal force?

Back

Centripetal force is the force that keeps an object moving in a circular path, directed towards the center of the circle.

Front

What happens to an object at rest when no net force acts on it?

Back

An object at rest will remain at rest if no net force acts on it, according to Newton's First Law of Motion.

Front

What is the effect of gravity on objects?

Back

Gravity is a force that pulls objects towards the center of the Earth, affecting their motion and weight.

Front

What is the significance of the net force in motion?

Back

The net force determines the motion of an object; if it is zero, the object remains at rest or in uniform motion.
