What factors determines the strength of the frictional force between two surfaces
how hard the surfaces push to gether the types of surfaces
involved
Which two surfaces would have the highest coefficient of friction
Two vectors which do not lie along the same line represent what kind of motion
Where would a bowling ball and a napkin fall with the same acceleration
In a vacuum chamber. C. On the moon.
Is Buoyancy an upward force exerted by a fluid on a body placed in the fluid
Yes, and the strength of the force is equal to the weight of the fluid displaced by the body.
True
Is it bad if you have a heavy period on one month and a light one the next month
No it is not bad, as some ladies have a heavy period for one
month and then a light one or they may have two heavy periods and
then one light one also.
In free fall all objects fall with the same acceleration
yes and that is 9.8m/s2
true
If an object floats the volume of the displaced water is equal to the volume of the whole object
The force needed to overcome kinetic friction is usually less than that needed to overcome static friction true or false
To calculate the density of a substance what two properties do you need to know
On a spinning ride at the fair it is inertia that keeps you moving in a circle
A negative slope on the velocity vs time graph indicates that the object is not accelerating true or false
Watching television with the remote control in your hand which of the following exerts the greatest gravitational force on you
The couch you are sitting on
Lily walked 2 blocks east then 1 block south How would you determine her total displacement
The total displacement will be calculated using Pythagoras
theorem. The distance traveled will form the two sides of the
triangle. Hence we have to calculate the hypotenuse side using the
formula Square root of (2 power 2 + 1 power 2)=Square
root(5)=2.23
Liquids that do not mix form into layers when they have different densities true or false
The of any amount of a solid liquid or gas relative to its volume is called it's density
How were slaves affected by the new republic
Some northern states made slavery against the law.
How long can you car be parked along freeway before towed
Which of newtons laws represents the equation Fma
Newton's 2nd law is F=ma.
Which of the following has the lowest density
What is the frictional force needed to slow an object in motion.
True or false an object buoyant force and weight arent the same thing
