What two things does force depend on
Answer:
When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance or (acceleration)
Explanation:
A 35kg cannonball sits at rest on a flat level surface. What is the normal force exerted on the cannon ball. Use -9.8 m/s2 for acceleration due to gravity.
A. -343N
B. 44.8N
C. 25.2N
D. 343N
Answer:
a) N = 343 [N]
Explanation:
We must remember Newton's third law, which tells us that the force acting on a body is equal to the normal reaction force of equal magnitude but acting in the opposite direction.
[tex]N=m*g[/tex]
where:
m = mass = 35 [kg]
g = gravity acceleration = 9.81 [m/s²]
[tex]N = 35*9.8\\N= 343 [N][/tex]

A pendulum swings back and forth. Is there energy in the system?
Answer:
yes
Explanation:
A pendulum should be able to contain enough energy to constantly be moving
There are three types of friction. ______________ friction occurs when an object is not moving. ______________ friction occurs when an object is moving against another surface. ______________ friction occurs in the case of wheels or other round objects. The amount of friction depends on two things.First, how ______________ the surfaces are; and second, how ______________ the object is. It is ______________ to keep an object moving than to start it moving. This is because static friction is ______________ than sliding friction.
Word Bank:
static
sliding
rolling
bumpy
heavy
easier
greater
Answer:
1. Static friction = not moving
2. sliding friction = moving
3. rolling friction = wheels
4. bumpy the surfaces are
5. how heavy the object is
6. it is easier to keep an object moving
7. static friction is GREATER than sliding friction
