Force and Motion

Front

What is a force?

Back

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

Front

What are balanced forces?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Forces that are not equal and can cause an object to accelerate or change direction.

Front

What is net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

How do you calculate net force?

Back

Add all the forces acting on an object, taking into account their direction.

Front

What is the unit of force?

Back

Newton (N) is the unit used to measure force.

Front

What is motion?

Back

The change in position of an object over time.

Front

What is inertia?

Back

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

Front

What is an example of a balanced force?

Back

A book resting on a table, where the force of gravity is balanced by the normal force of the table.

Front

What is an example of an unbalanced force?

Back

A soccer ball being kicked, where the force of the kick is greater than the friction holding it in place.
