Basics 1
Any object with this will exert gravity on every other object
what is mass
Inertia in motion
What is momentum?
Gravity does not depend on this
what is volume
The equation for momentum
p=m x v
p=momentum
m= mass
v= velocity
The direction of momentum is the same as this.
What is velocity?
The force responsible for planetary orbits
What is Universal Gravitation
The amount of momentum a stationary object has
What is zero?
What is the momentum of a 1500 kg car going at highway speed of 28 m/s
What is 42,000 kg m/s
Acceleration depends on
What is Earth's mass and objects distance
Can momentum be pasted on to another object?
Yes
Momentum is described by
What is direction and velocity?
Alice and Bob are traveling at equal velocity of 60 m/s North but Alice weights 55 kg and Bob weighs 60 kg which will have a greater momentum?
What is Bob?
Does not affect the rate of free fall.
What is mass?
F=MA
What is Newton’s 2nd Law Equation
Moving object 1 towards object 2 and/or increasing the mass of one or both objects will do this.
What is increase the attraction?
1. Which object has the least momentum?
Object A: m = 1 kg, v = 100 m/s
Object B: m = 10 kg, v = 12 m/s
Object C: m = 0.5 kg, v = 1000 m/s
Object D: m = 100 kg, v = 2 m/s
What is Object A?
When compared to earth's gravity the gravity exerted by everyday objects is this.
What is Negligible
This part on a car absorbs the energy from another car when in an accident.
All objects accelerate towards Earth at
What is 9.8m/s2
Which has more momemtum, a 3.0 kg mass moving at 9.0 m/s or a 5.0 kg mass moving at 5.0 m/s?
What is 3.0 kg mass moving at 9.0 m/s?
