What happend to the space pod in missing seconds?
Answer:
From our investigation of what forces are like in a collision, we learned that when two
objects collide, a force is exerted on each object. The two forces are in opposite
directions but the same strength. This allowed us to infer that an equal strength force
was exerted on the space station and the pod, but in opposite directions.
As a result, the space station and the pod are moving in opposite directions. We need to
learn more about the effects of collisions on each object’s motion so we can report back
to Dr. Gonzales at the space agency.
You will use physical materials to gather data about
forces in a collision. You will also notice how objects
are affected by collisions. Students will use their
data to infer the force direction for objects in a
collision.
Based on the velocity change of each object,
what did you infer about the direction of forces
during a collision?
• We observed that the velocity of each object changed during a collision, so we can infer
that a force had to be exerted on each object. However, the motion of the objects
changed in different ways.
• The object that was moving forward slowed down, so I can infer that the force must have
pushed backward on this object.
• The other object started moving forward, so the force must have pushed forward on that
object. If one force was backward and one force was forward, then the forces pushed
the objects in opposite directions.

why a small car can stop easier than an 18 wheeler while traveling at 70 mph down the interstate?
You and your 3 friends are driving down the road. All the wheels go flat at the exact same time, that's not good. You have to use a 2,100 N force to push the car 4 meters to the side of the road. How much work did you do on the car?
Answer:
Workdone = 8400 Nm
Explanation:
Given the following data;
Force = 2100 N
Distance = 4 meters
To find the work done;
Workdone = force * distance
Workdone = 2100 * 4
Workdone = 8400 Nm
Therefore, the amount of work done on the car is 8400 Newton meters.

why Newton law of gravitational force is called universal law
Answer:
Newton's law of gravitational holes good irrespective of the nature of two bodies., i.e., big or small, at all times, at all locations and for all distances in the universe.
Explanation:
It is called so because it is applicable on all bodies having mass, and the bodies will be governed by the same law, that is newton's law of gravitation. Thus, as it is applicable universally, it is called as universal law.
In order to increase the final momentum of a golf ball, we could
a) follow through when hitting the ball
b) increase the force acting on it
c) increase the time of contact with the ball
d) swing as hard as possible
f) All of the above
Answer:
option f) all of the above
We will see that all of the given options would increase the momentum, so the correct option is f "all of the above"
How to increase the momentum?
Momentum is defined as the amount of motion, and it is given by:
P = m*v
Where m is the mass of the object and v is the velocity.
We can't change the mass of the golf ball, but we can change the velocity, and to do it, we need to increase the acceleration that we apply to the ball.
To increase the acceleration we can:
follow through when hitting the ball (the force is applied for more time, so the acceleration is larger).increase the force acting on it (it directly increases the acceleration).increase the time of contact with the ball (similar to the first option).swing as hard as possible (similar to the second option).Then all the options are correct, which means that the correct option is f.

The law of conservation of energy states:
Energy increases exponentially with time
Total energy decreases due to energy output.
Energy cannot be created or destroyed.
Energy always remains in the same form.
Answer:
Energy cannot be created or destroyed.
Explanation:
its in the name, law of "conservation" of energy. energy can only change forms not be destroyed
Answer: Energy cannot be created or destroyed.
Explanation: The law of conservation of energy states that energy can neither be created nor be destroyed due to energy loss. It can only change its states from one energy state to another.
The efficiency is defined as the ratio of output work to the input work. The efficiency of the fan is not 100%. Because some of the energy is lost in the form of heat and sound. No machine is 100% efficient. There is always some loss of energy takes place.

A tugboat is pulling a barge into a harbor. The barge is exerting a force of 3000 N against the tugboat.
Available options are:
A. –4500 N
B. –2500 N
C. 2500 N
D. 4500 N
Answer:
-4500 N
Explanation:
Given that we have F₁ = 3000N? (force of the barge)
the force of the tugboat is F '
To pull the barge, the force of the tugboat must be greater than or equal to the force of the barge.
Hence, according to Newton's third law which states that for every action or force in nature, there is an opposite reaction.
Therefore considering the available option the correct answer is "- 4500N, " this is because it is greater than the force of the barge and it's in opposition to the force exerted.
Answer:
The answer is -4500 N

A car traveling at 5m/s starts to speed up after 3 seconds its velocity has increased to 11 m/s what is its acceleration
Answer:
a=(v-u)/t
Explanation:
a =(11-5)/3
a= 8/3
a= 2.6 m/s
The acceleration of the car is 2 m/s².
What is acceleration?Acceleration is the rate at which speed and direction of velocity vary over time. A point or object going straight ahead is accelerated when it accelerates or decelerates.
Even if the speed is constant, motion on a circle accelerates because the direction is always shifting. Both effects contribute to the acceleration for all other motions.
Acceleration is a vector quantity with and SI unit of it is meter/second².
Given parameters:
Initial speed of the car: u = 5 m/s.
Final speed of the car: v = 11 m/s.
Time interval: t = 3 second.
Change is speed = final speed - initial speed
= 11 m/s - 5 m/s
= 6 m/s.
Hence, its acceleration is = change in speed / time interval
= 6/3 m/s²
= 2 m/s².
