You drop a ball from a very tall building. If g = 10m/s2, how far does it fall after 3 seconds?
What is this object’s velocity at a) 2 seconds and b)8 seconds?
If a ball, initially at rest, rolls down a ramp 3meters in the 1st second… what is it’s velocity after 3 seconds?
Change in speed- change in speed / time-speeding up / slowing down / changing direction
Speeding up in the positive directionorslowing down in the negative direction
On a distant planet, a man falls off a cliff. He falls 147 meters in 7 seconds. What is the acceleration due to gravity?
DAILY DOUBLE -wager up to your scoreIf you throw a ball in the air 80 feet, how long does it take to land?
A car starts at 100km/s and ends up at 40 km/s after 12 seconds. What was it’s acceleration?
You drop a ball from a plane. How fast is it going after 5 seconds?
You drop a ball from a plane on the moon (gmoon = 1.5m/s2). How fast is it going after 6 seconds?
You drop a ball from a plane. What is it’s position after 4 seconds?
You drop a ball from a plane on Jupiter (gjupiter = 25 m/s2). How far does it fall after 4 seconds?
Who stated that gravity pulls on all objects equally, therefore regardless of mass, everything falls at the same rate (ex. A golf ball and a bowling ball)
On a whiteboard, draw any x vs. t graph that depicts an object speeding up then slowing down
Does this graph tell you if there is initial velocity or not?
Yes it does. There is initial velocity since it’s initial slope is greater than zero.
A Ferrari goes 0 – 60 in 3 seconds. What is it’s acceleration?
A car is traveling 50 mph. It speeds up to 60 mph in 2 seconds. What was it’s acceleration for that period of time?
You throw a ball straight in the air. It takes 10 seconds to land. How high did it go?
