Name ________________________________ Lesson 1 How do Forces Affect Motion ____________________ - A push or a pull on an object that can cause it to change direction. ______________________ moves, stops, or changes direction without ______________________. Heaver objects ______________________________________________ _________________________________________________________. _____________________________ - a force that pulls two objects toward each other because of their mass, such as you toward the center of the earth. Mass – a measurement of the amount of material (matter) that makes up an object. Weight - is a measurement of how hard the earth’s gravity pulls on an object. The more mass an object has the more it ________________________. More ____________ = More _____________ = More ______________ Everything with mass has a gravitational pull. You have mass therefore you have ___________________. Do you have a lot of it? _______ Who is this guy? _________________________________________________________ Tell 2 cool things he did He discovered that objects will continue moving in a straight line until a force causes it to slow down or stop. He also discovered that an object not moving, or at rest, will stay at rest until a force, such as a push or a pull, moves it. This is called inertia, and is Newton’s 1st law of motion (He has 3) _________________________ -The tendency of a moving object to stay in motion or resting object to stay at rest. So when I kicked the soccer ball it went for ever right? ____________ What slowed it down and made it stop? _______________________ __________________________- is a force that slows down the motion of moving object. Name 2 things an object can have friction with. 1. ___________________________________ 2. ___________________________________ - - - - - - - - - - - - - - - - - - - - - - - - - Lesson 2: How does Energy Affect Motion ________________________ - The ability to do work. _____________________________ - The energy that an object has because of its position. Types of potential energy include: Sitting at the top of a slide At the highest point on a swing _____________________________________________ _____________________________________________ _____________________________________________ _____________________________________________ ___________________________ - The energy of motion Types of kinetic energy include: Going down the slide Moving on the slide __________________________________________________ __________________________________________________ __________________________________________________ __________________________________________________ Other Forms of Energy ___________________________ - The kind of energy an object has because it can move or because it is moving. Mechanical Energy can be potential or kinetic energy. ___________________________ - the energy that comes from chemical change. Chemical energy is a type of potential energy. Types of chemical energy include: A battery (not in anything) Gasoline (in a can) ______________________________________________ ______________________________________________ ____________________________ - The energy that comes from the flow of electricity. - - - - - - - - - - - - - - - - - - - - - - - - - Lesson 3: How are work and Motion related? __________________________ - the result of a force moving an object. When you push or pull something and it moves you have done work. The amount of work you do depends on how much force you use and how far the object moves. If you push or pull on an object really hard and it does not move, then you have not done work. _______________________________ - a machine made of one or two parts. Simple machines make work easier. Type of simple machine Definition a flat surface with one side higher than the other (ramp) Wheel and Axel A simple machine with slanted sides Lever A lever is a stiff bar that rests on a support called a fulcrum which lifts or moves loads Picture A Simple machine that uses a rope and a wheel to move an object Screw An incline plane wrapped around a rod. ______________________________ - a machine made of two or more simple machine. Label the different simple machines in this compound machine. _________________________ - a machine made up of many compound and complex machines. Like a car, truck, plane, or tractor
