You are viewing: Which One Of The Following Describes An Object In Motion
3 What is the SI or metric unit for distance?Miles Grams Meter Feet 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
4 What is used for comparison to tell if an object is in motion?direction reference point Speed velocity 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
5 What is the formula needed to calculate speed of an object?distance x time distance / time time / distance acceleration x time I need help!
6 Joe Shmoe walks 30 meters in 10 seconds. What was his speed?5 meters/second 3 seconds/meter 3 meters/second I need help!
7 What is the only difference between speed and velocity?Speed is more complex while velocity is less complex. Velocity is time divided by distance and speed is distance divided by time. Velocity requires a direction while speed does not. Speed and velocity are calculated differently. I need help!
8 Which of the following is an acceptable unit for velocity?Meters per second Feet per hour Miles per hour South Miles per hour I need help!
9 You are asked to create a graph that shows the speed of an objectYou are asked to create a graph that shows the speed of an object. What should be plotted on the x and y axes? Y axis = speed; X axis = time Y axis = time; X axis = distance Y axis = distance; X axis = time Y axis = time; X axis = acceleration
10 What is this graph showing?A person walking at varying speeds. A person walking at a constant speed and then stopping to rest. A person standing still. A person walked three miles.
11 What does this graph show?Distance Time D The object is not moving. The object is moving at a constant speed. The object is moving at a constant speed then stopped to rest. The object is moving at varying speeds.
12 What does a steep slope of a line on a distance time graph indicate?Speed is fast Speed is slow The object is not moving Speed is changing

13 Which of the following is NOT an example of acceleration?Walking in a straight line at a constant speed Approaching a stop sign A ball rolling down a hill Turning around a corner at a constant speed 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
14 Which of the following best describes a decrease in speed?Positive Acceleration Negative Acceleration Constant velocity Average speed 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
15 Suzie is running around a track at a constant speed of 5 m/sSuzie is running around a track at a constant speed of 5 m/s. Why is she accelerating? She is running at a constant speed She is changing direction She is speeding up She is slowing down 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
16 What is plotted on the y-axis when graphing acceleration?Speed Time Distance Acceleration 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
17 Force is measured in units of…m/s Newtons m/s2 grams
18 What is the net force? 10 N to the left 10 N to the right 0 N 10 N
19 What is the Net Force? 10 N to the left 10 N to the right 0 N 10 N
20 Which of the following arrows represents the force of friction?B A C D A B C D
21 Which one of the following forces opposes motion?gravity friction applied force centripetal force
22 Why does the Earth have more gravity than the moon?The moon revolves faster than the Earth The moon has less mass than the Earth Earth is a greater distance from the sun. The Earth has more water on it. I don’t know – I need help!
23 Ignoring air resistance, what object will hit the ground first when each is dropped from the same height? Baseball Bowling ball Both will hit at same time I don’t know- I need help!
24 Which statement best describes gravity?Gravity pushes objects towards Earth Gravity acts on all objects unless they are moving Gravity pulls objects towards Earth Gravity acts the same way on Earth as on the moon I don’t know – I need help!

25 An object reaches its terminal velocity when…the force of gravity is greater the force of gravity and the force of air resistance are balanced the force of air resistance is greater I don’t know – I need help!
26 The tendency of an object to resist a change in motion isGravity Friction Inertia Momentum I don’t know – I need help!
27 The greater the mass of an object…the lesser the gravity. the greater the inertia. the lesser the force. the lesser the inertia. I don’t know – I need help!
28 Which will have the greatest inertia?Bowling ball Baseball Tennis Ball Ping pong ball I don’t know- I need help!
29 Your parent presses the car brakes while driving …which of the following describes your motion?Your body moves backward Your body does not move Your body moves forward Your body remains at rest I don’t know – I need help!
30 Newton’s Second Law states that…Objects in motion stay in motion. Objects at rest stay at rest. If a net force is applied onto an object, it will accelerate. For every action there is an equal and opposite reaction. I don’t know – I need help!
31 You are having difficulty pulling a pile of books in a wagonYou are having difficulty pulling a pile of books in a wagon. What would be the best way to increase the acceleration of the wagon? Remove some books from the wagon. Add some books to the wagon. Remove the wheels from the wagon. Have a friend help you get on an exercise program I don’t know – I need help!
32 I don’t know – I need help!A person pushes a 10kg shopping cart down the isle. The cart accelerates at a rate of 2m/s2. How much force did he exert on the cart? 5 N 12 N 20 N 5 kg I don’t know – I need help!
33 What will happen to this object if the forces are applied?The object will accelerate to the left. The object will accelerate to the right. The object will stay at rest. The object will not accelerate. I don’t know – I need help!
34 Which of the following situations best illustrates Newton’s Third Law of Motion?A boy pulling a wagon, which accelerates. Inflating a balloon and releasing it. Moving forward when a car stops. I don’t know – I need help!
35 Which of the following describes Newton’s Third Law of Motion?Objects at rest stay at rest. If you apply a net force, acceleration will occur. Objects in motion stay in motion. For every action there is an equal and opposite reaction. I don’t know – I need help!

37 How does Newton’s 3rd Law apply to your ability to walk?Ground pushes down and your foot pushes up. Your foot pushes down with a greater force and the ground pushes back with a lesser force. Your foot pushes down on the ground and the ground pushes back with an equal force. I don’t know, I need help.
