Answer: 1- A diagram showing the forces acting on the object.

2- The force vector describes a specific amount of force and its direction. You need both value and direction to have a vector.

3- A vector quantity has a direction and a magnitude, while a scalar has only a magnitude. You can tell if a quantity is a vector by whether or not it has a direction associated with it.

4- I don’t know

5- When two forces acting on an object are equal in size but act in opposite directions, we say that they are balanced forces

6- By applying an unbalanced force, you can change the motion of an object. Unbalanced forces can make an object at rest start moving, make a moving object stop, or change the direction and speed of the object.

7- If the forces on an object are unbalanced, this is what happens: a stationary object starts to move in the direction of the resultant force.

8- Imbalance or unequal force

9- The result is no motion. Balanced forces can cancel each other out. Any time there is a balanced force, the object does not move.

10- net force is the vector sum of all the forces that act upon an object.

1. To demonstrate all the forces acting on an object.
2. They tell us about the direction of the force and the magnitude of the force relative to the other forces acting.
3. Larger vector arrows demonstrate a larger magnitude of a certain quantity. Vice versa.
4. In which direction are all of the forces in the diagram?
5. It means that there is no net force on the object - the forces sum up to zero. Forces are balanced if they are equivalent and in opposite directions.
6. Unbalanced forces ALWAYS CAUSE ACCELERATION (speeding up / slowing down). If an unbalanced/net force acts on an object, that object will ALWAYS accelerate in that direction for as long as the force is applied.
7. It means that there IS a net force acting on the object, aka the sum of the forces is greater than zero.
8. Net forces. Symbolized by Fnet or Greek letter Sigma before the F.
9. Absolutely no CHANGE IN motion. This is Newton’s First Law of Motion - basically all objects continue in their state of motion unless acted on by an unbalanced force. Note if an object is already moving and balanced forces act on it, it will continue moving. No change in motion.
10. It is the vector sum of the forces acting on an object in a certain direction.

Hope this helped! You were pretty much spot on for most of them, but I tried to add a little more detail in the responses I wrote. Please let me know if you have a question about this. Have a great night (or day)!

(1 point) A pilot flies in a straight path for 1 hour and 30 min. She then makes a course correction, heading 10 degrees to the
kati45 [8]

Answer:

The pilot is 2214.22 miles from her starting position

Explanation:

Since the pilot is traveling at a constant speed of 635 mph, the total distance traveled can be easily found as follows:

1stleg: d_{1} = 1.5*635 = 952.5 mi\\2ndleg: d_{2} = 2*635 = 1270 mi

There was a 10 degrees deviation, so the angle between the trajectory of both legs is 170 degrees.

The distance we need to find is that from the start of the first leg to the end of the second leg, those three distances form a triangle and since the side we're interested in is opposite to the 170 degrees angle, we can determine its length by the law of cosines:

d_{3}^{2} =d_{1}^{2} + d_{2}^{2} -2*d_{1}*d_{2}*cos(170)\\d_{3}^{2} =952.5^{2} + 1270^{2} -2*952.5*1270*cos(170)\\d_{3}=2214.22mi

The pilot is 2214.22 miles from her starting position

In the Biomedical and Physical Sciences building at MSU there are 135 steps from the ground floor to the sixth floor. Each step
satela [25.4K]

Answer:

W = 16.5 Kj

P = 49.9 Watt

E = 16471

Explanation:

m = 73.5kg

t = 5min 30sec = (5×60) + 30 = 330sec

each step = 16.6cm = 0.166m

h = 135×0.166 = 22.41 m

g = 10 m/s²

(i) W = F × s = W × h = mgh

W = 73.5×10×22.41 = 16471.35

W = 16.5 Kj

(ii) Power = workdone/time

P = 16471.35/330

P = 49.9 Watt

(iii) The energy burnt in this process = 16471

Why does a lorry travelling at 30mph have more kinetic energy than a car travelling at the same velocity?
rjkz [21]

Answer:

Because it has more mass

Explanation:

To understand this, think about the equation of kinetic energy

KE = \frac{1}{2} m v^{2}

Kinetic energy depends on both the velocity (v) as well as the mass (m).

Because a lorry is bigger and heavier than a car, it will have more mass. With more mass, at the same velocity the lorry with have more kinetic energy.
