Force is simply a push or a pull exerted on an object in order to change the motion of the object. ... Force can change the acceleration of an object. This acceleration can be a change in speed or direction of the object.
Scientists express force using a unit called newton (N).In mechanics, acceleration is the rate of change of the
velocity of an object with respect to time. Accelerations are vector quantities (in that they have magnitude and direction). The orientation of an object's acceleration is given by the orientation of the net force acting on that object.
Answer:
Distance, x = 5.7 m
Explanation:
We have,
Acceleration of the car is -8.7 m/s²
It is required to find how far will the car travel while coming to a complete stop if its initial speed was 10 m/s. Using third equation of kinematics to find it as :
So, the distance covered by the car is 5.7 m.
According to the gravitational force law, force existing between two objects is proportional to the mass of the two objects and inversely proportional to the square of the distance between them. When masses are doubled each. Then the force increases 16 times.
Answer:
24.4 m
Explanation:
sin 30 = 12.2 / x
x = 12.2 / sin 30 = 24.4 m
Answer:B
Explanation:
Because the Earth's core isn't moving around earth therefore the center of Earth will forever be warm
