Balanced and Unbalanced Forces

Front

What are balanced forces?

Back

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

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and opposite, causing a change in the motion of an object.

Front

What happens to an object when balanced forces act on it?

Back

The object remains at rest or continues to move at a constant speed in a straight line.

Front

What happens to an object when unbalanced forces act on it?

Back

The object will accelerate in the direction of the net force.

Front

How do you calculate net force?

Back

Net force is calculated by adding all the forces acting on an object, taking into account their direction.

Front

If a 10 N force to the right and a 5 N force to the left act on an object, what is the net force?

Back

The net force is 5 N to the right.

Front

What is the net force if two 20 N forces act in opposite directions?

Back

The net force is 0 N, meaning the forces are balanced.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, making it harder to change its motion.

Front

What is the relationship between force and motion?

Back

A force applied to an object can change its speed or direction, resulting in motion.
