This law is in action when you slam on the brakes and everything in your car flies forward.
What is Newton's 1st law?
100
A horizontally launched projectile will land at this time compared to an object dropped straight down from the same height at the same time.
What is at the same time?
100
Any object at rest has this much momentum.
What is 0 kgm/s?
100
kg
What is mass?
200
Positive and negative signs on vector quantities indicate this.
What is direction of motion?
200
This law is applied to launch rockets with supplies for the International Space Station.
What is the 3rd Law?
200
This is the only net force causing a projectile to accelerate.
What is gravity?
200
This is defined as ANY change in momentum.
What is impulse?
200
m/s
What is velocity?
300
This is the displacement of an football player who ran the ball from the 42-yard line to the 10-yard line.
What is -32 yards? (10 yds-42 yds)
300
This force always opposes gravity for an object at rest on a surface.
What is normal force?
300
The absence of this is the reason that projectiles are not accelerating horizontally.
What are horizontal forces?
300
An object experiencing a change of momentum of 15 kgm/s experiences this much impulse.
What is 15 Ns?
300
N
What is force?
400
This is how much time it takes a car driving 20 m/s to cover 360 meters of distance.
What is 18 seconds? (360 m/20 m/s)
400
According to Newton's 2nd law of motion, an object with 3x as much mass as another object requires this much extra force to accelerate equally.
What is 3x as much force?
400
A projectile launched at a rate of 20 m/s that takes 10 s to reach the ground will land this far away from its launch point.
What is 200 m? (20 m/s*10 s)
400
A 1500 kg car that has a velocity of 20 m/s is traveling with this much momentum.
What is 30,000 kgm/s? (1500 kg*20 m/s)
400
J
What is impulse?
500
This is the total change in velocity of a car accelerating from the access road to the highway at a rate of 4 m/s/s in 6 s.
What is 24 m/s?
500
This is the acceleration of an object with 80 kg of mass that is being pushed to the right with 50 N of force, with 10 N of friction opposing its motion.
What is 0.5 N/kg or 0.5 m/s/s? (Fnet = 50 N-10 N= 40 N; a = 40 N/80 kg)
500
A projectile that takes 15 s to reach the ground has been dropped from this height.
What is 1102.5 m? (4.9*15^2)
500
An 1800 kg car traveling 20 m/s comes to a stop, so this is its change in momentum.
