What is the relationship between the change in velocity and force?

change in velocity =accleration. Suppose a car is moving at 30km\hr at 6:30 am and then the velocity of the car is noted to be 100km\hr at 7:30am.thus the change in velocity of the car =100-70=30 km\hr over a time of (6:30am-7:30am) 1hr.Thus the accleration of the car=30km/hr*hr.Force however is the product of the mass of the car and the accleration by which the car is travelling.Let the mass of the car be 100kg.Thus the force =100*30=3000kg*km/hr*hr.


Imagine you are pushing a shopping cart what do you need to know in order to calculate how much force you are applying?

You would only need to know the accleration of the cart, and it's mass. Since there are wheels on the cart, you shouldn't have to worry about friction. It is as simple as newtons second law Force = mass times accleration. If you know two of these quantities, you can solve the equation for the third. Hope this helps!


When is the accleration of a body is positive?

The acceleration of a body is positive when the body is speeding up in the direction of its velocity. This occurs when the force applied to the body is in the same direction as its motion, causing it to accelerate positively.


What is a transformed equation?

A transformed equation is a new equation derived from an original equation by applying mathematical operations such as addition, subtraction, multiplication, or division. These transformations help simplify or manipulate the equation to solve for a specific variable or to represent it in a different form.


What is one half accleration times time squared?

This is the physics formula for displacement, more commonly called distance. But, it assumes you start at zero speed. The time units cancel out in the formula, so the answer comes out in terms of distance.
