Students must:
-Copy the word and definition in their journal.
-Write a sentence for each vocabulary word. The vocabulary words will be used in the sentences.
-Draw a picture tht will help the student remember the word/definition.

1. Force - Forces are pushes and pulls. Every motion starts with a force.

2. Balanced Force - Balanced forces that are equal in size and opposite in direction.

3. Unbalanced Force - Unbalanced forces change the motion of an object. They occur when one force is greater than the others.

4. Friction - Friction is caused when 2 objects rub aganinst each other. Friction makes an object slow down or stop moving.

5.Air Resistance - Air resistance is friction between an object and air.

1. 1st Law of Motion – An object at rest will stay at rest and an object in motion will stay in motion at a constant velocity unless acted upon by an unbalanced force.

2. 2nd Law of Motion –
Force = Mass x Acceleration
This formula shows that both the size of the force and the mass of the object itself affect the object’s acceleration.

3. 3rd Law of Motion – For every action, there is an equal and opposite reaction.

4. Newton – Force is measured in a unit called a Newton. (N)

5. Inertia – The tendency of an object to keep its same motion. (Another name for the 1st law of motion.)

1. Speed – Speed is how fast an object is moving. The formula for finding speed is distance divided by time.

2. Velocity – Velocity is the speed and the direction of an object.

3. Acceleration – Acceleration is how fast an object changes its velocity. Acceleration occurs when a moving object speeds up, slows down, or changes direction.

4. Momentum – Momentum is a property of motion. It depends on the mass and velocity of an object.

5. Joule – SI unit of measurement for energy or work. When used as a unit the j is always written as a capital. (J). Joule was named for James Prescott Joule, an English physicist.

1. Simple Machine – A machine with few or no moving parts that makes it easier to do work.

2. Compound Machine – A machine made of two or more simple machines working together.

3. Lever – a simple machine made of a bar that rotates, or turns around a fixed point called the fulcrum. It is used to lift weight

4. Effort – Force applied to a simple machine.

5. Resistance – Force exerted by something you are trying to move.

6. Fulcrum – Point around which a lever pivots or rotates.

1. Pulley – A simple machine made of a wheel with a groove around the outside. It needs a rope, cable or belt to make it do work by changing the direction of a force.

2. Wheel and Axle – A simple machine made of a wheel fixed to a rod, or axle; both rotate together. The wheel turns on a post to help move things quickly and easily

3. Inclined Plane – A simple machine made from a slanted/sloped surface that is higher on one end, used to make lifting easier

4. Wedge – A simple machine made from two inclined planes together used to raise and object, split an object, or hold an object in place.

5. Screw – A simple machine made from an inclined plane wrapped around a pole or shaft that is used to hold materials together or drill holes.

1. Rotation – The time it takes to spin on its axis (1 day)

2. Revolution – The time it takes to orbit the sun once (1 year)

3. Orbit – The elliptical path an object takes in space while revolving around another object.

4. Moon – A natural satellite of a planet.

5. Gravity – The force that governs the motion of our solar system.

6. Planets – large bodies that orbit a star.

1. Comet – mixture of ices, dust and rocks with an elliptical orbit around the sun. Radiation from the sun causes a tail to form, that points away from the sun.

2. Galilean Moons – The largest of Jupiter’s moons. They are Io, Europa, Ganymede and Callisto.

3. Meteoroids – Rocky fragments of comets, planets, moons, or asteroids without an orbit.

4. Meteors – Meteoroids that have entered an atmosphere.

5. Meteorites – Any part of a meteoroid that survives passage through the atmosphere and lands on the surface of a planet or a moon.

6. Asteroids – Left over rocks or metals from the formation of the solar system that are smaller than a planet but larger than a meteor.
