Concepts
A force is required to change the velocity of an object
What is required to change the velocity of an object?
Speed in a particular direction
What is velocity?
to reach a conclusion using evidence and reasoning
What is an inference?
It is a property of matter
What is important about inertia
Lighter chairs change velocity more easily than heavier ones
Why are lighter wheelchairs better for racing?
How an object changes velocity depends on the direction of the force exerted on that object
A push/pull that can change the motion of an object
What is force?
the amount of matter that makes up an object
What is mass?
Mass and Velocity are proportional to each other
What is it called when mass and velocity have a relationship that as one changes, so does the other?
Heavier wheelchairs are more stable
Why are heavier wheelchairs better for rugby?
What causes a greater change in velocity?
An event or process that leads to a result/change
What is a cause?
small engines of a pod
What are thrusters?
The object's velocity is zero
If an object is at rest, what is its velocity?
Wheelchairs that are in between the weight of racing and rugby wheelchairs.
Compared to racing and rugby, what is the weight of a basketball wheelchair?
Understanding a cause-and-effect relationship can help you infer what led to a particular result
A result or change that happens because of an event or process
What is effect?
used to refer to another object/place/thing to show direction of something
what is frame of reference?
Also called deceleration
What is negative acceleration also called?
Rugby wheelchairs
What wheelchairs are more heavy than the standard?
If the same strength force is exerted on two objects but the objects have different masses, the object with less mass will have a greater change in velocity
When the same strength force is exerted on two objects with different mass, which would have the greater change in velocity?
A force between an object and the surface it is moving over
what is friction?
to change the motion of an object, an external force must be applied
What is Newton's First Law of Motion?
something that changes
What is a variable?
Racing wheelchairs
What wheelchairs are lighter than the standard?
