Inertia

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object; the greater the mass, the greater the inertia.

Front

What is net force?

Back

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 of motion.

Front

What does it mean when forces are balanced?

Back

Balanced forces occur when two or more forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What does it mean when forces are unbalanced?

Back

Unbalanced forces occur when the total 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 inertia?

Back

An object's mass is a measure of its inertia; a larger mass means greater inertia, making it harder to change its motion.

Front

What is the relationship between net force and acceleration?

Back

According to Newton's second law, the net force acting on an object is equal to the mass of the object multiplied by its acceleration (F=ma).

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 happens to a moving object when balanced forces act on it?

Back

A moving object will continue to move at a constant velocity if balanced forces act on it, as there is no net force to change its motion.

Front

What is an example of unbalanced forces in everyday life?

Back

An example of unbalanced forces is when a person pushes a stationary car; if the force applied is greater than the frictional force, the car will move.

Front

How do curved paths relate to unbalanced forces?

Back

When an object moves in a curved path, it is experiencing unbalanced forces, as the direction of the velocity is changing, requiring a net force to act towards the center of the curve.
