Chap 5 & 6

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its motion. It is not equal in size and opposite in direction to other forces acting on the object.

Front

What happens when a force pushes in the opposite direction of a moving object?

Back

The object will slow down and eventually stop.

Front

What is the role of gravity in keeping objects on the ground?

Back

Gravity pulls objects toward the Earth, keeping them grounded unless acted upon by another force.

Front

What is a balanced force?

Back

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

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons through a conductor.

Front

What can electrical energy be transformed into?

Back

Electrical energy can be transformed into light energy, sound energy, thermal energy, and mechanical energy.

Front

What is a circuit?

Back

A circuit is a closed loop that allows electricity to flow, consisting of a power source, conductors, and a load.

Front

What is the function of a switch in a circuit?

Back

A switch controls the flow of electricity in a circuit, allowing it to be turned on or off.

Front

What happens when a light bulb is replaced with a doorbell in a circuit?

Back

The circuit will produce sound instead of light, as the doorbell transforms electrical energy into sound energy.

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, components are connected one after another, while in a parallel circuit, components are connected across common points, allowing multiple paths for current.
