Static Electricity
On a cold day, you may see a person’s hair stand up straight. The reason the hair stands up is static electricity. Static electricity is an electric charge that builds up in an object.
Lightning is one example of static electricity. A static charge builds up in a cloud, and then current electricity moves to the ground in the form of a lightning flash. You may even hear a crackling noise.

What happens when you plug a lamp into a wall outlet? Electricity flows from wires in the wall through the plug and into the lamp’s wires. Electricity that moves through a wire is current electricity.
A lamp’s bulb glows only when there is a closed circuit. A circuit is a path that electricity follows. Electricity moves from the wall outlet, through the lamp, and back to the wall.
People use current electricity to light, heat, and cool homes, to run motors, and to cook food. What other things do you know of that use electricity?
MAIN IDEA AND DETAILS What is current electricity?

How Electricity Moves
Electricity moves through some things but not through others. Something that electricity moves freely through is called a conductor. Copper wire is a good conductor.
Something that electricity will not move through easily is called an insulator. Wood and plastic are examples of insulators. Electricity can be dangerous, so people use insulators to stay safe.
MAIN IDEA AND DETAILS What is a conductor? What is an insulator?

Lesson 2: What Are Forces?
VOCABULARY
Types of Forces
To move a ball, you can throw it, kick it, or hit it with a bat. Any kind of push or pull is a force. You must apply a force to make an object move. An object will keep moving until another force stops it. When you catch a moving ball, the force from your hand stops the ball.
Friction is one force that stops things or slows them down. When two objects rub together, there is friction between them. Most rough surfaces make more friction than smooth surfaces. You can slide farther on the ice than you can on dirt or grass.
Forces also make objects change directions. You apply a force to the handlebar to turn your bike. When you push one end of a seesaw down, the other end comes up.
Some forces do not even have to touch the object. A magnet can be used to push or pull objects made of iron or steel. This is called magnetic force. A magnet can pull a nail.

|
MAIN IDEA AND DETAILS A magnet picks up paper clips. What force is at work?
|
Ways That Forces Change Motion
Three things affect the motion of an object.
• the strength of the force
• the direction of the force
• the mass of the object
The stronger the force is, the greater the change in motion. If you toss a ball gently, it doesn’t move fast or far. If you throw a ball hard, the ball moves faster and farther. You use more force on the ball when you throw it as hard as you can.
If an object is not moving and a force pushes or pulls it, the object will move in the direction of the push or pull. When you pull up on an object, it comes up. When you push an object to the right, it moves to the right.
The smaller the mass of an object is, the easier it is to move. It takes less force to pick up a pencil than to pick up a book since a pencil has less mass.
You can add all the forces that push or pull on an object. The sum is called the net force. Suppose you and a friend push the same way on a door. The net force on the door equals your push plus your friend’s push.
|
|
MAIN IDEA AND DETAILS Name three things that affect the motion of an object and tell what each one does.
|
When equal forces act in opposite directions, they cancel each other out. The net force is zero.
Why does the waterfall back down to Earth after shooting up from the fountain?
Gravity
When you throw a ball into the air, you know that it will come
back down. Gravity is a force that pulls two objects toward each other. The
ball comes back to Earth because Earth’s gravity pulls on it.
Gravity is a very weak force between most objects. You don’t feel
the force of gravity between you and your desk. But Earth’s gravity pulls very
strongly. This is because Earth is so large.
The force of gravity depends on how much mass an object has. Weight is a measure of the force of gravity on an
object. Objects with a large mass weigh more.
