Explain the relationship between force, acceleration, mass, momentum, and impulse

Physics
1 answer:
Tomtit [17]3 years ago
5 0
Force is mass times acceleration same as F= m x a ; this means a object with a larger mass needs a stronger force to be moved along at the same acceleration as an object with a small mass. 
The momentum and impulse states that the change in momentum of an object is equal to the impulse applied to it. the equation for this one would be; F= m x a same as the force and acceleration equation. 
I don't know if this really helped, but I tried my best so hopefully you get it, if not tell me I will try to explain it more. :)

You drive your car for 2.0 h at 40.0 km/h then for 2.0 h at 60.0 km/h what is your average velocity?
Verdich [7]
In order to calculate velocity, we'd need to know the straight-line distance between the start and the finish, and we'd also need the direction of that line.  The best we can do with the information given in the question is calculate the average SPEED.

Average speed = (total distance covered) / (time to cover the distance).

Distance covered in the first 2 hours = (2 hr) x (40 km/hr) = 80 km.
Distance covered in the second 2 hours = (2 hr) x (60 km/hr) = 120 km.

Total distance covered = (80 + 120) = 200 km
Time to cover the distance = (2 + 2) = 4 hours

Average speed = (200 km) / (4 hours)  =  50 km/hour

A van traveling down a slope with a uniform acceleration of 2.15 meters/second2 attains a speed of 20.00 meters/second after 7.0
ANEK [815]
Final velocity = initial velocity + (acceleration*time)
That is v = u + at
So 20 = u + (2.15*7)
20 = u + 15.05
Thus, u = 20 - 15.05
= 4.95 meters/second
that is C

2. A tiny pig is dropped from the top of a building and lands safely on a trampoline. The tiny pig will have
allsm [11]

Answer:

c. Kinetic energy

Explanation:

The two types of energy involved in this problem are:

- Potential energy: it is the energy possessed by an object due to its position. It is calculated as

PE=mgh

where

m is the mass of the object

g is the acceleration due to gravity

h is the height of the object relative to the ground

From the formula, we see that the higher the object is above the ground (higher h), the larger the potential energy of the object. In this problem, the pig is falling down, so the value of h is decreasing, therefore the potential energy is decreasing as well.

- Kinetic energy: it is the energy possessed by an object due to its motion. It is given by:

KE=\frac{1}{2}mv^2

where

m is the mass of the object

v is its speed

In this problem, as the pig falls down, it accelerates, so its speed increases: since the kinetic energy is proportional to the square of the speed, as the speed increases, its kinetic energy increases too. So, the correct answer is

c. Kinetic energy
