The energy which is possessed by an object because of its motion is called Kinetic energy.
Example:
- Wind mills. Energy is formed by the motion of wind mills, so it is kinetic energy.

Answer:
W = 7591.56 J
Explanation:
given,
distance of the box, d = 37 m
Force for pulling the box, F = 217 N
angle of inclination with horizontal,θ = 19°
We know,
Work done is equal to product of force and the displacement.
W = F.d cos θ
W = 217 x 37 x cos 19°
W = 7591.56 J
Hence, the work done to pull the box is equal to W = 7591.56 J
Answer:
Explanation:
Givens
m = 942
F = 6731
t = 21 seconds
vi = 0
vf = ?
Formula
F = m * (vf - vi ) / t
Solution
6731 = 942*(vf - 0)/21 Multiply both sides by 21
6731 * 21 = 942*vf
141351 = 942*vf Divide by 942
141351/942 = vf
vf = 151 m/s
Answer:
The answer is 8.44*10^9 Newton
Explanation:
The equation for universal gravitation is:
Where:
G= 6.674×10^−11 N · (m/kg)^2
M(earth)=5.972 × 10^24 kg
M(asteroid)=5.0×10^13 kg
r=1.537*10^9 m (Calculated from average distance between moon and earth)
The force will be:
8.44*10^9 Newton
