Answer: In the 5th dimension, they who claim to know, say that there is only one time, including the past and the future.
Yes potential increases while kinetic decreases
Gravity ALWAYS does that, and electrostatic force does it when two objects have opposite charges.
Answer:
Total energy=Kinetic energy+Potential energy
Explanation:
the total energy will be obtained from the energy of an object in motion and the energy stored in the object
Answer:
1 Nm
Explanation:
Given;
Force = F = (4, 3, 3)N
Position 1 = P = (3, 3, -1)m
Position 2 = Q = (2, -1, 4)m
The object moves along a straight line path from P to Q, therefore, the distance vector (d) is given by;
d = Q - P
d = (3, 3, -1) - (2, -1, 4)
d = (1, 4, -5)m
Now the work done (W) by the force (F) to move through the distance (d) is the dot product of the two vectors: F and d. i.e
W = F . d
For clarity, let's write vectors F and d in vector unit notation as follows;
F = 4 i + 3 j + 3 k
d = 1 i + 4 j - 5k
Therefore,
W = (4 i + 3 j + 3 k ) . (1 i + 4 j - 5k)
W = (4 + 12 - 15)
W = 1
Therefore, the workdone by the force is 1 Nm
