During parkour, a person leaps at a wall and performs a flip. What must they do to change
directions?
6
Answer:
they push off the wall with a force greater than the wall
Explanation:
The game of parkour involves moving from one point to another and performing several skills which includes flips, especially in a difficult environment.
To change directions, the person must exert a significant force on the wall.
When the person leaps on the wall, it means the person moves or jumps quickly on the wall.
While this is being carried out, the concept of force must be applied.
If the force that acts on a stationary object is smaller than the required force to move the object, the object's position remains unchanged.
This means that for the person's direction to change, the person must exact a great force (or a significant force) enough to cause a change in direction.

which of the following quantities can be measured in the same units as Work?
speed times velocity, momentum time speed, forces times velocity, kinetic energy, mass times acceleration, kumquats, potential energy, momentum, weight times acceleration
Answer:
Kinetic energy and potential energy.
Explanation:
Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v^2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared. Kinetic energy is usually measured in units of Joules (J); one Joule is equal to 1 kg m^2 / s^2.
The formula for potential energy depends on the force acting on the two objects. For the gravitational force, the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m/s^2 at the surface of the earth) and h is the height in meters. Notice that gravitational potential energy has the same units as kinetic energy, kg m^2/s^2. In fact, all energy has the same units, kg m^2/s^2, and is measured using the unit Joule (J).
Work is also measured with the unit Joule (J).
