Definitions
When an object resists a change in motion.
Inertia
A person runs 100 m in 12s, what is his/her speed
8.33 m/s
Newton's explanation of inertia
Newtons 1st law
The velocity for formula
(v = d/t)
The term to describe changing from a liquid to a gas
Vaporization
The measure of inertia
Mass
The net force of a combined force of 7 N north with a force of 5 N south
Newtons law that states that for every action there is an equal and opposite reaction
Newtons 3rd law
Newtons 2nd law of motion
F = ma (where F = force, m = mass, a = acceleration)
The universal solvent
Water
The amount of work an object/person does per second is
Power
How much force is needed to accelerate a 70kg rider and her 200 kg motor scooter at 4 m/s/s
1080 N
What Newton's law is a bird flying through the air.
Newtons 3rd law
Kinetic Energy
(where KE = kinetic energy, m = mass, v = velocity)
The four most familiar states of matter
Solid,liquid,gas,and plasma
The force that opposes motion between two surfaces that are touching
Friction
The force necessary to accelerate a 1,250 kg car at a rate of 40 m/s/s
50,000 N
According to Newton's 1st law, what will a moving object not acted on by an unbalanced force do?
Continue to move at a constant velocity
work
(where W = work, F = force, d = displacement)
A homogenous mixture
A mixture uniform throughout
The substance being dissolved in a solution
Solute
The mass of the basketball being thrown with a net force of 9 N and accelerates at 1.5 m/s2
6 kg
The law of motion that discusses the relationship between force, mass, and acceleration
Newtons 2nd law
Power
(where P = power, W = work, t = time)
A heterogenous mixture
Mixture not uniform throughout
