What is a collision?
occurs when two or more objects come into contact with each other
occurs when two are more objects are moving towards each other
occurs when objects are moving
occurs when objects do not touch each other
What is contact?
occurs when two or more objects physically touch each other
occurs after a collision
occurs when an object changes shape
occurs when two or more objects are travelling towards each other
What is damage?
a permanent change in the shape of an object
a temporary change in the shape of an object
always occurs when a collision occurs
never occurs when a collision occurs
What is force?
a push or pull on an object resulting from its interaction with another object
a permanent change in shape of an object
the energy of motion
energy transfer from one object to another
What is energy transfer?
the process of energy moving from one object, system, or location to another
the energy an object has because it is moving
the energy an object has because of its position
the heat of an object during a collision
What is Kinetic Energy?
the energy an object has because it is moving
energy moving from one object to another
energy an object has because of its position
heat energy
When objects collide, (a) is transferred from one object to another, which results in a change in (b) .
When objects collide, one or more (a) push on one or more objects, which results in a change in (b)
What causes the change in motion for colliding objects?
energy transfer
heat
chemical reactions
forces
What causes the change in shape for colliding objects?
energy transfer
heat
chemical reactions
forces
All solid objects (a) bend or change shape when pushed in a collision.
A force that objects experience due to contact with another object is called...
Contact Force
Kinetic Energy
Free Body Diagram
Breaking Point
The term (a) is used to describe a bend or change of shape of an object.
What unit is used for measuring force?
Newtons (N)
Centimeters (cm)
Inches (in)
Pounds (lb)
A (a) is a tool used to measure force.
(a) : A factor to control or change in an investigation.
An Independent Variable is the variable that is (a) each time you test.
A Dependent Variable is the variable that is (a) each time you test.
A Control Variable is the variable that is (a) each time you test.
The Line of Best Fit is:

A line used to connect all data points
A curved line drawn to represent a pattern in the data that can be used to make predictions
A line drawn on the X or Y axis

A
B
C
D
(a) : the maximum amount of force a material can withstand before it is permanently deformed
(a) : the stress level at which the material breaks
When two objects make contact, each object applies a force on the other object on the surface they touch. The strength of those objects are (a) but in (b) directions.
Peak Force:
the maximum amount of force on an object during a collision
the bend or change of shape of an object
the energy an object has because it is moving
the maximum amount of force a material can withstand before it is permanently deformed
Free Body Diagram:
a visual representation that shows an object and all of the forces that act on it
straight line drawn to represent a pattern in the data that can be used to make predictions
the maximum amount of force a material can withstand before it is permanently deformed
the stress level at which the material breaks
Increasing the speed or mass of a moving object...
Increases its Kinetic Energy (KE)
Decreases its Kinetic Energy (KE)
Does not change its Kinetic Energy (KE)
The more KE objects have, the (a) peak forces they produce during a collision.
Objects that collide apply (a) peak force on each other.
During contact, objects apply (a) strong forces to each other in (b) directions.
Different objects have (a) elastic limits and breaking points.
Which of the following does NOT affect how much an object deforms, its elastic limit, and its breaking point.
Type of Material
Thickness
Shape
The type of material, shape, and thickness of an object affects all of the following EXCEPT:
Amount of Deformation
Elastic Limit
Breaking Point
Peak Force
(a) solid objects deform elastically, up to a point.
(a) solid objects bend or change shape when pushed on in a collision and when other contact forces are applied to them.
Energy transfer occurs (a) a collision.
There is a force between objects when they make (a) during a collision.

Bird
Plane
Both objects have the same amount of kinetic energy
Neither object has any kinetic energy.

3 Cars (A, B, and C) are all travelling the same speed. Car A and B collide with each other head-on. Car C collides with a brick wall. Which of the scenarios described has the greatest amount of peak force in the system.
The collision between Car A and Car B
The collision between Car C and the brick wall
Both scenarios have the same amount of peak force in the system
Two cars travelling in towards each other collide head-on. Which of the following shows the correct force arrows for the system?
In free body diagrams, the direction of the arrow shows the (a) of the force on the object and the length of the arrow shows the (b) of force on an object.
