Answer:
Explanation:
Displacement is the change in the position of an object.
Abigail runs a complete lap around the track, which is 400 meters. Even though she ran 400 meters, she has <u>no displacement.</u> If she starts and ends at the same spot, there is no change in position.
Gabi runs a 50 meter dash in a straight line. Gabi has <u>50 meters of displacement</u>. She runs in a straight line and is 50 meters away from where she began.
While Abigail ran the farther distance, <u>Gabi had the greater displacement.</u>
Answer:
The gravitational potential energy of that rock is 174371.4 J.
Explanation:
Given
- Mass m = 59.31 kg
- Height h = 300 m
To determine
We need to find the gravitational potential energy of the rock
We know that the potential energy of a body is termed as the stored energy due to its position.
One kind of energy comes from Earth's gravity — Gravitational potential energy (GPE).
Gravitational potential energy (GPE) can be determined using the formula
where
is the mass
is the gravitational acceleration which is equal to g = 9.8 m/s²
is the height
- GPE is the Gravitational potential energy
now substituting m = 59.31, h = 300 and g = 9.8
J
Therefore, the gravitational potential energy of that rock is 174371.4 J.
