2.
momentum
incorrect
3.
constant speed
incorrect
4.
3rd Law
incorrect
5.
Unbalanced Force
incorrect
6.
Friction
incorrect
7.
speed equation
incorrect
8.
Balanced Force
incorrect
9.
speed
incorrect
10.
acceleration
incorrect
11.
average speed
incorrect
12.
motion
incorrect
13.
Force
A.
rate of change in velocity
B.
speed that does not change over time
C.
force acting on an object that will NOT change the object's motion
D.
A force gives energy to an object, sometimes causing it to start moving, stop mofing or change direction. A push or a pull
E.
distance divided by time
F.
A force that acts in a direction opposite to the motion of the moving object. Friction will cause a moving object to slow down or stop.
G.
mass x velocity
H.
Laws of motion
I.
a change in postion in a certain amount of time
J.
Every action has an equal and opposite reaction.
K.
force that acts on an object that will change its direction
L.
the rate at which an object moves
M.
final distance divided by final time
Type the Answer that corresponds to the displayed Question.
incorrect
14.
Types of Friction
Type the Question that corresponds to the displayed Answer.
incorrect
15.
speed in a given direction
incorrect
16.
(final velocity-orginal velocity)divided by time
incorrect
17.
Occurs when objects move accross or through fluids or gases
incorrect
18.
a decrease in velocity
incorrect
19.
Force = mass x acceleration (the larger the force the larger the acceleration)
incorrect
20.
Inertia - an object a rest remains at rest and an object in motion remains in motion unless acted upon by an unbalanced force.
incorrect
21.
speed that changes over time
incorrect
22.
When solid objects slide over each other
incorrect
23.
Produced by such objects such as wheels or ball bearings. Tends to be less than sliding friction.
