Back

A force is a push or pull that can change the motion of an object.

Front

What are balanced forces?

Back

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

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that cause an object to move or change its motion because they do not cancel each other out.

Front

What is magnetic force?

Back

Magnetic force is the attraction or repulsion between objects that have a magnetic field, like magnets.

Front

How do you know if forces are balanced?

Back

Forces are balanced if the object does not move or moves at a constant speed.

Front

How do you know if forces are unbalanced?

Back

Forces are unbalanced if the object starts to move or changes its speed or direction.

Front

What happens when two students push a box in the same direction?

Back

The box moves faster in the direction they are pushing.

Front

What happens when one student pushes a box to the left and another pulls it to the right?

Back

The box may not move or may move slowly, depending on the strength of the forces.

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces that are in contact.

Front

What is an example of a magnetic force?

Back

An example of a magnetic force is when two magnets attract or repel each other.
