We have been working HARD to understand forces.
Students have had LOTS of hands on practice going through experiments to understand how forces work.
Aiming for a vocabulary quiz next week. List of words is at the end of the post.
Social Studies:
We have started Week 9 of Studies Weekly about Jamestown. Students have been given a paper copy of the lesson so they can look over it at home.

Vocabulary _ Force and Motion
- Force—A push or a pull that one object exerts on another object with or without direct contact (e.g., friction, gravity). Causes a change in speed or direction.
- Push or Pull:
- Balanced forces—forces that are equal in size but opposite in direction.
- Unbalanced forces—forces that are unequal in size and may or may not be opposite in direction.
- Types of Force:
- Buoyant force -the upward force exerted on an object by water.
- Gravitational force - the pull of all objects in the universe on one another.
- Magnetic force - the force produced by a magnet.
- Friction—a force that opposes motion through direct contact
- Measurement of Force
- Net force - the combination of all the forces acting on an object.
- Newton – (N) the unit of measuring force
- Weight—a measure of the force of gravity on an object.
- Motion – the change in position of an object over time with respect to a reference point.
- Position - the location of an object in space.
- Acceleration – the rate at which velocity changes
- Speed—the distance traveled by an object in a given amount of time. Measured in distance per time, such as miles per hour (mph)
- Inertia - the property of matter that keeps it at rest or moving in a straight line.
- Velocity – the speed of a object in a particular direction
