ID kinematics
This is the acceleration at the very top point on the path of a projectile.
What is 9.8 m/s/s?
A motorcycle speeds horizontally off a 50m high cliff. How long is the motorcycle falling?
3.194 s
An interaction between two objects that result in pushing or pulling the objects.
What is Force?
Since momentum has both magnitude and direction it can be classified as this.
What is a vector?
This is the amount of force applied over a certain distance or Blank = Force x distance
What is Work
This is the distance that a ball released from rest will fall during the 2nd second if it traveled distance H during the first second.
What is 3H?
A football is kicked with an initial velocity of 20 m/s at an angle of 37 degrees. How long is it in the air?
2.45 s
F = ma
What is Newton's 2nd law equation?
This is the name we give for the change in momentum.
What is impulse?
This the rate at which work is done or Blank = Work/time
What is Power
This is the value that can be found from the area under a velocity-time graph.
What is displacement?
A balloon launcher fires balloons with an initial velocity of 25 m/s at an angle of 38 degrees. How far away does it land?
61.8 m (t=3.14)
The tendency of an object to resist a change in motion.
What is Inertia?
This is the final velocity a 500 kg car that starts at rest will have after it is rear-ended by a 650 kg that is initially going 20 m/s. The cars lock together after they hit.
What is 11.3 m/s?
This is the unit that Work is measured in.
What is a Joule (J)/What are Joules (J)
This is the type of acceleration that an object must have in order to be able to use the top three equations on your equation sheet.
What is constant?
You shoot a cannon horizontally from a height of 196 m. The cannonball is projected horizontally at 8.5 m/s. How far away does the cannonball land?
53.7 m (t=6.32)
The force of gravity (weight) of a teenager a)7N b)70N c)700N d)7000N
What is c)700N?
A 5 kg loaded rifle is initially held at rest and then fired. The 0.05 kg bullet leaves the barrel at 450 m/s. This is the final momentum of the bullet-gun system.
What is zero?
This is the unit that power is measured in blank.
What is Watts
This is how long it will take a 5 kg object to hit the ground if dropped from rest at a height of 12.5 m. You can ignore air resistance.
What is 1.60 seconds?
A football is kicked with an initial velocity of 20 m/s at an angle of 37 degrees. What is the maximum height of the ball?
7.38 m (t=2.45)
An applied force that always acts perpendicular to the surface in contact.
What is Normal Force?
This is the symbol used to represent angular momentum.
What is L?
This happens to power when you increase the amount of work done.
What is increasing your power, increasing the power, increasing power
