Define distance
The change of velocity per unit of time.
Speed that does not vary over time.
How far between two objects or locations
In math or physics, the steepness of a line on a graph.
The location of an object is its
slope
position
gravity
force
"If you run the same distance in less time, are you going faster or slower?" (Fossweb: Gravity and Kinetic Energy)
faster
slower
"A hawk flew 600 m in 1 minute. A sparrow flew 400 m in 30 seconds. Which bird was faster?" (Fossweb: Gravity and Kinetic Energy)
Hawk
Sparrow
The steeper the slope the __________ the animal is running.
faster
slower
The interaction between masses-the push or pull.
position
slope
acceleration
force
When Usain Bolt starts to slow down at around 70 meters, we say he is _________________.
accelerating
moving at a constant speed.
decelerating
speeding up
The force of attraction between objects with mass.
force
position
gravity
slope
When an object is moving at the same speed over a period of time
acceleration
constant speed
average speed
deceleration
The slope of a position (x) vs time (t) graph is the object's ______.
Change in position (Δx)
Change in speed (Δv)
speed (v)
acceleration (a)
A steeper slope on a position (x) vs time (t) graph indicates a ______________________.
slower speed
faster speed
slower acceleration
faster acceleration
An object that does not move at a constant speed is ___________________.
slowing down
speeding up
accelerating
not moving
True or False. Usain Bolt ran at a constant speed throughout his 100m race.
True
False
True or False. If the slope of a position (x) vs time (t) graph changes/curves, the object is accelerating
True
False
True or False. A falling object increases speed with constant acceleration, no matter how massive it is
True
False
Why do some objects fall slower than others on Earth
Air resistance
gravity
Different weight
different materials
Two bowling balls, identical in size, are raised 20m above the Earth. Ball A weighs 8 pounds and Ball B weighs 16 pounds. What will happen if both balls are dropped at the same time? (Assume the air resistance is the same for each object)
Ball B will strike the ground in half the time as Ball A because Ball B is twice as massive
Ball B will strike the ground sooner than Ball A due to it's weight, but not in half the time due to air resistance
Ball A will strike the ground sooner than Ball B because Ball A is lighter
Ball A and Ball B will strike the ground at the same time
Two pieces of paper are dropped at the same time from a height of 10m. One piece of paper is flat and the other is crumpled into a ball. Which piece of paper will hit the ground first? (Assume this takes place on Earth, and not in a vacuum)
The crumpled ball of paper will hit the ground first
The smooth, flat piece of paper will hit the ground first
Both pieces will hit the ground at the same time
More information is needed to determine which ball will hit the ground first
Which is larger? 1 km or 1dm
1 km
1 dm
