Motion
The unit for force
What is a Newton?
kgm/s2
What is a N?
This is the difference between weight and mass.
What is Weight is how gravity acts on an object, mass is the amount matter in an object?
If Jack walks 8 blocks north and 5 blocks west. Displacement is this, while distance is this.
13 blocks = distance
9.4 blocks NW = displacement
Objects that sink displace this.
What is their volume?
Rubber does not allow electrons to flow easily making it a good ______________.
What is insulator?
Velocity of an object at rest.
What is 0 m/s?
A hammer and a feather are dropped at the same time on the moon. They both reach the ground at the same time because this is missing.
What is there is no air, so all objects will fall at the same rate?
The forces acting on a ball thrown into the air.
What is air resistance and gravity?
Buoyant force on an object that displaces 25 kg of freshwater.
What is 250N up?
Objects that float displace this.
What is fluid equal to their mass?
A piece of wood contains this kind of energy.
What is chemical?
What is acceleration due to gravity in formulas
If a tennis ball was thrown off the top of NGC and hit the ground in 3.2 seconds. Speed will it be traveling when it hits the ground.
What is 32 m/s?
I drop a pebble and a rock from the same height, the order they hit the ground.
What is they hit at the same time?
The difference between Speed and velocity
What is a velocity requires direction and is a vector ?
In acceleration formula, what does Vi stands for this.
What is Initial Velocity?
Units of Resistance, current and voltage
What are ohms, amperes and volts?
If a ball is dropped from 143 meters, this will its velocity be when it hits the ground.
(it takes 5.4 secs to hit the ground)
What is 53 m/s?
Flat line on speed time graph shows this.
What is constant velocity?
If Jacob throws a ball straight up (on earth) at the rate of 40.4 m/s, how long would it go up until it stopped going up and started to fall?
What is 4.04 seconds?
If Berkley is driving his golf cart at 10m/s and comes to a complete stop in 4 seconds, This is his acceleration.
What is -2.5 m/s2?
This force acts in the opposite direction of motion.
What is friction?
Energy caused by vibrations.
What is sound?
The distance a car travelled if it drove at 40 m/s for 30 minutes
What is 72 km?
D = v*t = 40 m/s * 1800 s
D= 72,000 m = 72 km
Displacement needs to include these two things.
What is magnitude and direction?
Buoyant forces act in these substances.
What are fluids? (Gas or liquid)
Fred runs the basketball court 5 times (from one side back to the other 5 times). Ending in his original starting place. This is Fred's displacement at the end of his run.
What is 0 meters? He ended where he started
An increase in this results in an increase in inertia.
What is mass?
This is the biggest source of radiant energy.
What is the sun?
