7PS12 - Balanced / Unbalanced Forces

Front

What are balanced forces?

Back

Equal forces acting on an object in opposite directions, resulting in no change in motion.

Front

What is velocity?

Back

Speed in a given direction.

Front

What is magnetism?

Back

The force of attraction or repulsion of magnets.

Front

What is net force?

Back

The sum of all forces acting on an object.

Front

What is friction?

Back

A force that opposes motion between two surfaces that are in contact.

Front

What are unbalanced forces?

Back

Forces that cause a change in the motion of an object because they are not equal and opposite.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the relationship between net force and motion?

Back

If the net force is zero, the object remains at rest or in uniform motion; if not, the object accelerates.

Front

What is the effect of balanced forces on an object?

Back

They do not change the object's motion.

Front

How does friction affect motion?

Back

Friction opposes motion, making it harder for objects to slide past each other.
