Test Description: Review
Instructions: Answer all questions to get your test result.
1) A force ...
A
is the amount of work done.
B
can be measured in kilograms.
C
always causes on object to move.
D
is a push or a pull.
2) If forces are in the same direction,
A
they will have the same acceleration.
B
they are always equal.
C
you add them to get the net force.
D
you subtract them to get the net force.
3) If forces are in opposite directions,
A
they are always equal.
B
you subtract them to get the net force.
C
you add them to get the net force.
D
they will have the same acceleration.
4) If the net force on an object is 60 N, then
A
the forces acting on it are unbalanced.
B
there is only force acting on it.
C
it will not move.
D
the forces acting on it are balanced.
5) If the net force on an object is 0 N, then
A
the forces acting on it are unbalanced.
B
the forces acting on it are balanced.
C
there are several forces acting on it.
D
it will move.
6) Emmy pushes on a box with 10 N of force to the left, while Claire pushes on the box with 8 N of force to the right. What will happen to the box?
A
It will move to the right.
B
It will not move.
C
It will move to the left.
D
Not enough information to determine if the box will move or not.
7) Work occurs when
A
a force is applied to an object and the object moves in the direction of the force
B
a force is applied to an object and the object moves in the opposite direction of the force
C
an object moves
D
a force is applied to an object and the object moves
8) You are dribbling a basketball down the court and pass the ball to your teammate. When did WORK occur on the ball?
A
when you dribbled the ball and when your teammate caught it
B
when you dribbled the ball and when you threw it down court to your teammate
C
only when you dribbled the ball
D
when you held the ball
9) At the end of science class, you pick up your binder and carry your things to your next class. When did WORK occur?
A
when you carried it to your next class
B
when you picked up the binder
C
when you picked up the binder and carried it to your next class
D
there was no work done
10) You pull on a locked door as hard as you can. Why wasn't there any work done?
A
WORK was done on the door
B
the door was broken
C
because you pulled on the door
D
the door did not move
11) Why do people use ramps to move heavy objects?
A
Because it takes less force to move an object up a ramp than lifting it
B
Because it would decrease the distance you had to move the object
C
Because they are lazy
D
Because it takes more force to move an object up a ramp than lifting it
12) When you use a ramp, it takes less force but you have to
A
push harder
B
make sure the ramp is twice as long as the mass of the object
C
accelerate the object more
D
move the object a greater distance
13) The WORK done when using a ramp
A
can't be determined
B
is more than when you lift the object straight up.
C
is less than when you lift the object straight up.
D
is the same as when you lift the object straight up.
14) What is formula for work?
A
Work = Force x acceleration
B
Work = mass x distance
C
Work = Force / distance
D
Work = Force x distance
15) What unit is WORK measured in?
A
Celsius
B
Newtons
C
Joules
D
Calories
16) If you pull a wagon with 25 N of force over a distance of 5 m, how much work have you done?
A
no work was done
B
5 J
C
29 J
D
125 J

A
three
B
one
C
four or more
D
two

A
dependent variable
B
independent variable
C
control
D
conclusion
20) Factors in an experiment that stay the same. (In the video, it would have been the amount of sunlight, type of soil, type of pot, type of plant, temperature of room, etc.)
