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 force, m is mass, and a is acceleration.

Define balanced forces.

Back

Balanced forces are two or more forces acting on an object that are equal in size but opposite in direction, resulting in no net force and no change in motion.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the total forces acting on an object are not equal, causing the object to accelerate in the direction of the net force.

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 at the same rate as lighter objects.

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 force, an increase in mass will result in a decrease in acceleration.

What happens to the net force when two equal forces act in opposite directions?

Back

When two equal forces act in opposite directions, they cancel each other out, resulting in a net force of zero.

Front

Explain the concept of net force.

Back

Net force is the overall force acting on an object after all the individual forces are combined. It determines the object's acceleration and direction of motion.

What is gravitational force?

Back

Gravitational force is the attractive force between two masses. On Earth, it pulls objects toward the center of the planet, giving them weight.

How do you determine the direction of acceleration?

Back

The direction of acceleration is determined by the direction of the net force acting on the object. If the net force is to the right, the acceleration will also be to the right.

What is the effect of friction on motion?

Back

Friction is a force that opposes motion between two surfaces in contact. It can slow down or stop the movement of an object.
