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