Vocabulary
#1 What is the change in position of an object called? motion
#2 An item that you pick out to determine if something is moving or not is called what? reference point
#3 The rate at which an object changes position is called what? speed
#4 Any push or pull of an object is called what? force
#5 What is it called when forces pull objects towards each other. gravity
Force & Motion
#1 What is it called when you know that you are moving and an object is not. relative motion
#2 Which object requires the most amount of force to move? A bowling ball or tennis ball a bowling ball
#3 If you and your friend are pushing the same weighted box, who will push the box farther? The person who uses more force.
#4 On which object would the force of gravity be the strongest? An elephant or a mouse an elephant
#5 The change in one object's position compared with another object's position is known as what? relative motion
Force & Motion
#1 What two things do you need to calculate velocity? speed and direction
#2 When you are riding on a roller coaster and it goes from a straight track to a turn, what is it an example of? acceleration
#3 What equation do you need to calculate the average speed of something? Speed=Distance/Time
#4 What are the three examples of acceleration? Something speeds up, slows down, or goes around a curve
#5 How is speed different than velocity? Velocity includes direction.
Calculate the Average Speed
#1 Riding your bike 20 miles in 4 hours 5 miles per hour
#2 Riding your bike 15 miles in 5 hours 3 miles per hour
#3 Riding your bike 18 miles in 2 hours 9 miles per hour
#4 Riding your bike 24 miles in 4 hours 6 miles per hour
#5 Riding your bike 50 miles in 5 hours 10 miles per hour
Miscellaneous
#1 If balanced forces are applied to moving object then what will happen? The objects keep moving at the same speed and direction.
#2 When we did the sandpaper and wax paper investigation with the cars, what were we investigating? Friction
#3 When doing something that requires a lot of effort like lifting something heavy, what would help? Combined forces
#4 If you pedal your bike on a flat surface with the same force for 5 minutes, then will your speed continue to increase? No
#5 Objects that do not seem to move define your what? Frame of reference
