What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined.

What does it mean for forces to be balanced?

Back

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

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces occur when the forces acting on an object are not equal, causing the object to accelerate in the direction of the greater force.

How does mass affect acceleration?

Back

According to Newton's second law, acceleration is inversely proportional to mass; as mass increases, acceleration decreases if the same force is applied.

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can occur due to a change in speed or direction.

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

Back

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

What is gravitational force?

Back

Gravitational force is the attractive force between two masses, such as the force that pulls objects toward the Earth.

What is an example of a balanced force?

Back

A book resting on a table experiences balanced forces: the downward gravitational force is equal to the upward normal force from the table.

Front

What is an example of an unbalanced force?

Back

A soccer ball being kicked experiences unbalanced forces; the force of the kick is greater than the opposing forces, causing it to accelerate.
