What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

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

Front

What is friction?

Back

Friction is the force that opposes the motion of two surfaces sliding past each other.

Front

What is inertia?

Back

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

Front

What is the force of gravity?

Back

Gravity is the force that pulls objects toward the center of the Earth, measured in newtons.

Front

What happens when forces are balanced?

Back

When forces are balanced, the object remains at rest or continues to move at a constant speed in a straight line.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the object will accelerate in the direction of the net force.

Front

What is an example of balanced forces?

Back

A book resting on a table is an example of balanced forces, where the force of gravity is equal to the normal force from the table.

Front

What is an example of unbalanced forces?

Back

A soccer ball being kicked is an example of unbalanced forces, where the force of the kick is greater than the opposing forces.

Front

What is the role of friction in motion?

Back

Friction slows down or stops the motion of objects sliding against each other.
