Newton's Laws of motion
Which law is 'every action has an equal and opposite reaction'?
Newton's 3rd Law
To which law does F = ma relate?
Newton's 2nd law
How do you work out distance?
speed x time
How many seconds does it take for the ticker timer to tick 5 times.
0.1s
Inertia
How are force and mass related?
if you change one, the other is impacted
Speed equals . . .
Distance/time
How do you define the equation ft = mv
impulse = change in momentum
Where to you observe Newton's 3rd law when performing the chair push activity?
As you touch it (it slightly pushes back)
or
As it touches the ground
A 0.50-kg cart (#1) is pulled with a 1.0-N force for 1 second; another 0.50 kg cart (#2) is pulled with a 2.0 N-force for 0.50 seconds. Which cart (#1 or #2) has the greatest acceleration? Explain.
Cart 2: they have the same mass, yet cart 2 has a greater force
How do you change km/h to m/s
divide by 3.6
if time equals 0.010s and impulse equals -40(N*s), what is force equal to is newtons?
-4000N
A piece of paper is quickly pulled out from under a 2L bottle of water with out it spilling. Define the law to which this relates
Newton's 1st law: the law of inertia
Define acceleration
A change in speed and/or direction as a result of force.
A racecar starts 36s into a video and finishes 3m11s later on a track that is 6.213km long. What is its average speed in m/s?
39.57m/s
how was force related to the increasing drop height in the egg drop simulation?
Force is directly related to drop height.
How can Newton’s laws be used to explain how rockets are launched into space?
Newton’s third law would tell us that when the rocket pushes out fire with a specific amount of force, the rocket will move in the opposite direction, but with the same amount of force. This is what causes the rocket to shoot up into the air.
If you have a mass of 15000g accelerating a speed of 100km/hr. what is the force in Newton's?
416.7N
Describe Tom Cruise's need in Top gun that relates to motion
He feels the need, the need for speed
One skateboarder, weighing 57kg pushes the other skateboarder who is 81kg with a force of 85N. What is the acceleration of the first skater?
a = F/m = 1.49m/s2
