Vocabulary
Position is the exact place something is located and direction is where an object is facing.
Name three different patterns of motion.
Spinning, up and down, side to side, etc.
Name three different types of forces.
Gravity, push, pull, friction, etc.
What is an example of a push force? What is an example of a pull force?
Push force: pushing in a chair, pushing a wheel borrow, etc.
Pull force: pulling out a chair, pulling a wagon, etc.
What is friction?
A force on an object going in the opposite direction.
This is described by using distance and time.
Speed.
Give an example of an up and down pattern of motion.
Seesaw, bouncing ball, etc.
What type of force is acting on a swing?
Push, pull, and gravity.
A box resting on a table has a net force of what?
0 Newtons.
What type of surface causes high friction? What type of surfaces causes low friction?
What are the three contact forces? What are the three noncontact forces?
Contact: tension, spring, friction
Noncontact: gravity, magnetism, electric
What pattern of motion does a swing have?
Up and down or swinging.
What can cause an object to move faster?
Greater amount of force.
Give an example of an unbalanced force.
A crane pulling a box, a weight swinging on a rope, etc.
How can friction affect the motion of an object.
The more friction acting on an object the slower it will move.
What is a balanced force? What is an unbalanced force?
A balanced force is two equal forces in the opposite direction. An unbalanced force is when one force is stronger than the other and there is motion.
Give an example of a spinning or rotational pattern of motion?
Bicycle wheel, ferris wheel, merry-go-round, etc.
Tension force is when an object is being pulled or stretched and spring force is when the object goes back to its original position.
Give an example of how more force acting on an object can cause the speed to increase?
Multiple people pushing a box, multiple people pulling a sled, etc.
Give an example of friction acting on an object.
Road and a tire, shoe on a carpet, etc.
What does pattern of motion mean?
A repeated movement of an object.
When does a magnet attract another magnet? When does a magnet repel another magnet?
A magnet attracts another magnet when the poles are unlike and repels another magnet when the poles are alike.
What forces are acting on a box sitting on a table?
Gravity is pushing down on the box and the table is pushing up on the box.
How can you make a surface have a lower friction? How can you make a surface have higher friction?
Add water or wax to make the surface have a lower friction and add salt or sand to make the surface have a higher friction.
