Explanation:
Energy transfer is the movement of energy from one location to another. For example, when electricity moves from a wall plug, through a charger, to a battery.
Energy transformation is when energy changes from one form to another – like in a hydroelectric dam that transforms the kinetic energy of water into electrical energy.
Explanation:
There are 5 kinematic equations, and 5 variables.
Each question will give you 3 variables and ask you to solve for a fourth.
To determine which equation to use, look at which variable is <em>not</em> included in the problem.
For example, if the question does not include time, then you need to use a kinematic equation that does not have t in it. That would be:
v² = v₀² + 2aΔx
Or, if the question does not include the final velocity, then you need a kinematic equation that does not have v in it. That would be:
Δx = v₀ t + ½ at²
Qs 1: m = 1/2*KE*V^2
qs 2: 6,223.39 kg
Answer:
Explanation:
From the question we are told that:
Generally the equation for Resolutions is mathematically given by
Where
Generally the equation for Direction is mathematically given by
If you increase the mass m of the car, the force F will increase, while acceleration a is kept constant. Because F and m are directly proportional.
If you increase the acceleration a of the car, the force F will increase, while mass m is kept constant. Because F and a are directly proportional.
How can Newton's laws be verified experimentally; is by setting this experiment, and changing one variable while keeping the other constant, then observe the change in F.
Hope this helps.
