What is the definition of balanced forces?

Back

Balanced forces are two or more forces acting on an object in such a way that they cancel each other out, resulting in no change in motion.

Front

What is the definition of unbalanced forces?

Back

Unbalanced forces occur when two or more forces acting on an object do not cancel each other out, causing the object to accelerate in the direction of the net force.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion, meaning an object at rest stays at rest and an object in motion stays in motion unless acted upon by a force.

Front

What happens to an object when the net force is zero?

Back

When the net force is zero, the object remains at rest or continues to move at a constant speed in a straight line.

If a balloon pushes air to the right, what is the reaction force according to Newton's Third Law?

Back

The air pushes the balloon to the left.

What is the net force acting on a wheeled cart moving at a constant speed with equal forces acting on it?

Back

The net force is zero, indicating that the forces are balanced.

Front

What is the formula to calculate net force?

Back

Net Force = Force applied - Force opposing.

What is an example of balanced forces in everyday life?

Back

A book resting on a table experiences balanced forces: the force of gravity pulling it down and the normal force from the table pushing it up.

What is an example of unbalanced forces in everyday life?

Back

A car accelerating forward experiences unbalanced forces when the engine's force exceeds the frictional force opposing its motion.

What is the effect of unbalanced forces on an object's motion?

Back

Unbalanced forces cause an object to accelerate, change direction, or change speed.
