Chapter 1
The SI unit for mass
What are kilograms
Represented by the symbol delta Δ
What is change
The trig function that represents the X direction
What is Cosine
The equation for force
What is Force= Mass x Acceleration
Newtons first law
What is a object at rest with stay at rest and a object in motion will stay in motion unless it is acted upon by an external force
The dimensional analysis for area
What is [L2]
Has both direction and magnitude
What is a vector
This is the relative velocity if you are in a car going 60 mph in relation to a car going 85 mph when they are travelling in the same direction
what is 15 mph
The two classes of forces
What are contact and action at a distance force
Newtons second law
What is the force action on an object is equal to the mass of that object times in acceleration. F=ma
The amount of sig figs in 0.0084
What is 2
Is equivalent to speed
What is distance/time
The range a ball will cover with a initial velocity of 20 m/s at and angle of 30 degrees to the horizontal
What is 34.4 meters
The acceleration of a 10 kg box being pushed across a flat surface with a constant force of 50 Newtons and the kinetic friction is 0.2
Netwons third law
What is for every action this is an equal and opposite reaction
The m/s equal to 50 mph when 1 mile=1609 meters
50 mi/hr (1hr/3600s)(1609m/1mi) = 22.35 m/s
The average velocity of a car traveling distance of 150 km in 3 hours in m/s given 1km=1000 m
What is 13.89 m/s
The maximum height of a basketball with the initial velocity of 15 m/s at an angle of 45 degrees to the horizontal.
What is 5.74 meters
The acceleration of a 5 kg object being pushed with a force of 20 N on a friction less surface
What is 4 m/s2
the acceleration due to gravity on Earth's surface
what is 9.8 m/s2
The amount of km/hr equal to 25 m/s when 1 m/s=3.6 km/hr
what is 90 km/hr
The acceleration of a car going from rest to a velocity of 20 m/s in 5 seconds
What is 4 m/s2
The time of flight of a arrow with an initial velocity of 25 m/s at and angle of 60 degrees to the horizontal
What is 4.42 seconds
The acceleration of a 10 kg box being pulled across a rough surface with a force of 50 N and the kinetic friction is 0.3
What is 2.06 m/s2
This concept describes the velocity of an object as observed from a particular reference frame
What is relative velocity
