Vocabulary
What is force?
Force is an energy that changes an object's direction and or speed.
What is energy transfer?
Energy transfer is when energy is relocated from one object to another.
Someone bowling a strike.
Force and motion are involved as the person throws the ball and it rolls down the lane. Then collision and energy transfer are involved as the ball collides with the pins. At first, the ball has potential energy right before it is released and then it has kinetic energy as it moves towards the pins.
What else would someone use a blueprint plan for besides a playground?
One answer: a house
Does a playground have all the types of energy and engineering terms we have learned?
Yes
What is motion?
Motion is the action or process of moving or being moved.
What is height energy?
Height energy is energy that comes from how high the object is from the ground.
A rollercoaster ride.
At the peak of a rollercoaster, there is potential and height energy.
There is kinetic energy and motion as the rollercoaster moves.
Why is a blueprint helpful in the engineering process?
It lets you make a design plan before building to plan where everything will go and how large or small it will be.
Give an example of potential and kinetic energy in a playground.
One possible answer: At the top of a slide you have potential energy and while you go down the slide you have kinetic energy.
What is a collision?
Collisions are when two objects exert forces on each other at the same time.
What is energy?
Energy is the ability to do work.
Archery
Potential energy occurs when the person pulls back the bow.
Kinetic energy and motion are present when the bow is released.
Energy is transferred from the person to the bow and the target.
The bow collides with the target.
Why is it important to be accurate with measurements in a blueprint plan and real life?
In the design and building process, measurement accuracy is important to ensure safety and accurate building in the space provided.
Give an example of force and motion on a playground.
One possible answer: Someone pushing someone on the swings.
What is potential energy?
Potential energy is stored energy.
What is engineering?
Engineering is a science that involves building, designing, and solving problems.
Someone zip lining
At first, there is potential energy before the person is in the air and once the person is in the air there is kinetic energy.
The person is in motion while they ride the zip line.
How is perimeter involved in engineering?
As you design something you must know the measurements and therefore know and plan the perimeter.
Give an example of a collision risk on a playground and how energy transfer would be involved.
One possible answer: Playground parts that are placed too close to one another leading to a collision between two people and energy transfer between them.
What is kinetic energy?
Kinetic energy is energy in motion.
What is speed?
Speed is the rate at which someone or something can move.
Jumping on a trampoline
The person is in motion as they jump (kinetic energy).
They collide with the trampoline every time they land.
Energy transfers back and forth from the person to the trampoline.
Give an example that involves all of the following terms.
Motion, force, potential energy, kinetic energy, height energy, collisions, and energy transfer.
One example: Someone pushes someone on the swings. Force is present as they push the person which results in motion. As the person on the swing is at the highest point they have height energy and potential energy. As they move they have kinetic energy.
When they jump off the swing they collide with the ground and transfer energy.
What must you consider in the design process of a playground?
The height and width
Safety (avoiding unsafe collisions)
Ensuring playground parts function correctly. (Involving force, motion, potential energy, kinetic energy, height energy, collisions, and energy transfer)
