Quarterly 2 Review-2016
Test Description: Review for Quarterly review 2016
Instructions: Answer all questions to get your test result.
1) How do we calculate speed?
A
Mass X Acceleration
B
Velocity / Time
C
Distance / Time
D
Distance X Mass
2) What is the difference between “balanced” and “unbalanced” forces?
A
Unbalanced forces cause motion.
B
There is no difference. They both cause motion.
C
Balanced forces cause motion.
D
Gravity is both balanced and unbalanced.
3) What can you say about direction of motion after you push someone?
A
They move in the same direction as the force.
B
They move in the opposite direction due to action/reaction.
C
They stop moving because of inertia.
D
They remain at rest.
4) If you are riding on a bicycle and cruising along at 15 miles per hour, how fast will you be going over the handlebars when you suddenly hit a car?
A
45 mph
B
15 mph
C
7.5 mph
D
30 mph
5) Why didn’t we also change the amount of force on the cars when we did our Hot Wheels Lab?
A
Force and mass were already our variables.
B
Gravity and friction counteract force.
C
The results wouldn’t be related to any one variable.
D
We would improve our data.
6) Why did we do multiple trials in all of our labs?
A
to have enough data to graph.
B
so you can make up data if it isn't turning out right.
C
to follow the lab's procedures.
D
to reduce the likelihood of inaccurate results
7) Which of these are supported by the data from the Balloon Rocket experiment?
A
As the mass increased, the distance traveled increased.
B
Mass had no effect on distance traveled.
C
As the mass decreased, the distance traveled decreased.
D
As the mass increased, the distance traveled decreased.
8) Which statement best explains the interaction of force and motion that caused the Balloon Rocket at rest to move?
A
To move the rocket, the force acting on the rocket must be unbalanced.
B
To move the rocket, the force acting on the rocket must be balanced.
C
To move the rocket, gravity acting on the rocket must decrease.
D
To move the rocket, gravity acting on the rocket must increase.
9) When reading a motion graph, the fastest object is shown with______.
A
Theline that increases then decreases.
B
no line can show speed.
C
The steepest line.
D
Thr flat line.
10) A grocery cart being pushed by a shopper will continue moving in the same direction at the same speed unless
A
All of the above.
B
the force of friction brings it to a stop.
C
it is acted upon by an unbalanced force
D
the shopper stops pushing on the cart.
11) If runner 1 goes 100 m. in 10 sec. and runner 2 goes 120 m. in 10 sec., who is faster and how do you figure it out?
A
Runner 2 is faster. He runs 10 m./sec because you divide 100 by 10.
B
Runner 2 is faster. He runs 12 m./sec because you divide 120 by 10.
C
Runner 1 is faster. He runs 12 m./sec because you divide 120 by 10.
D
Runner 1 is faster. He runs 100 m./sec because you multiply 10 by 10.
12) Which will accelerate the most with the same amount of force?
A
A large ball
B
A small ball
C
A medium ball
D
It doesn't matter
13) If 2 teams are competing in a tug of war and no one is winning, the forces are
A
are accelerating
B
balanced
C
unbalanced
D
changed by gravity
14) If a runner has a speed of 20m./sec., how far will they travel in 5 seconds?
A
100 m.
B
20 m.
C
15 m.
D
4 m.
15) Glass 1 is on a shelf 4ft. high and glass 2 is on a shelf 8ft. high. What can you say about their potential energies?
A
Glass 2 has twice the potential energy since it is only half as high.
B
Glass 1 has twice the potential energy since it is only half as high.
C
Glass 2 has twice the potential energy since it is twice as high.
D
Glass 1 has twice the potential energy since it is twice as high.
16) Which example below is when heat is transferred from one object to another without the presence of matter?
A
Sitting down on a metal chair in the sun.
B
Sun warms the atmosphere of earth.
C
Stove heats a pot.
D
Cooking a pot of soup on the stove.
17) What is the correct order of transformations in a flashlight?
A
chemical--mechanical--light--electrical
B
chemical--electrical--light
