Question Column True or False If you push on an object, the object pushes on you.
Answer Column True
Question Column Draw a graph that shows a car moving and then stop
Answer Column The graph will show a line going up or going down and then horizontal.
Question Column Missy, Soni, and Sally all swim on a swim team. Missy swims the 50 meters in 10 seconds, Sally swims the 100 meters in 50 second, and Soni swims the 200 in 10 seconds. Rank the order from 1 (slow) to 3 fast).
Answer Column Sally 2 m/sec 2. Missy 5 m/sec 3. Soni 20 m/sec
Question Column If you want to find out if your dog or cat is the fastest, what two things do you need to measure?
Answer Column Distance and Time
Question Column In the ramp experiment, which ramp height will give the car the most speed?
Answer Column The higher the ramp, the faster the speed
Question Column What are four things a force can do to an object?
Answer Column Speed up, slow down, change direction, or change shape
Question Column What is an unbalanced force and give an example.
Answer Column An unequal force causes an object to move. Examples – a team winning tug of war.
Question Column ObjectWeight Eraser1.5 grams Paper0.5 grams Paper clip1.0 grams A student is testing how the weight of an object affects distance traveled. Which item above will go the farthest, and why do you think so?
Answer Column The piece of paper because it is the lightest.
Question Column What is motion?
Answer Column A change in position
Question Column Which item would have the largest gravitational pull? A basketball, a marble, a bowling ball or they all have the same pull
Answer Column A bowling ball
Question Column If several people push a stalled car, what force is overcome at the moment the car begins to move?
Answer Column friction
Question Column If I am in a car that stops suddenly, what will happen to me and why?
Answer Column I will continue to move forward until the seat belt stops me, because anything in motion will stay in motion (me) until a force acts on it (seatbelt).
Question Column TrialWeightNewtonsSpeed g1035 m/sec g20 In the experiment above, what is the speed of the second trial? Why do you think so?
Answer Column The speed should be double or 70 m/sec because if you double the force, you double the speed.
Question Column How can you make an object move?
Answer Column Apply a force
Question Column What is an balanced force? Give an example
Answer Column Forces that are equal and opposite. Nothing is moving. A book on a desk.
Question Column If you push an object that weighs 50 kg and an object that weighs 100 kg with the same force, how will the speed be affected?
Answer Column The lighter object will be faster.
Question Column During recess 3 students walked the path for their activity. Molly walked 200 meters in 4 minutes, Ari walked 400 meters in 8 minutes, and Vanessa walked 700 meters in 7 minutes. Who walked the fastest and explain your thinking.
Answer Column Vanessa walked the fastest. Molly’s speed was 50 meters in one minute, Ari’s speed was 50 meters in one minute, but Vanessa’s speed was 100 meters in one minute.
