Both horizontally and vertically, the net force acting on the car must be zero. However, a constant force is required to maintain its motion at a constant speed, therefore the net force vertically must be zero.
How do you find net force?
- As opposed to the net force acting on an item, it is frequently simpler to measure the mass and acceleration of the object.
- With the aid of a balance, one may determine the mass of an object, and one can get the average acceleration using time and velocity.
- But there's a chance that the net force is a result of a number of invisible forces, including air resistance, surface friction, and gravity. As a result, understanding how to determine an object's net force based on its mass and acceleration might be more helpful.
- It is possible to rewrite the aforementioned equation for acceleration as follows to solve for net force:
Net Force = Mass Acceleration, or
F = m × a
- In the figure below, have a look at Zeke's pal Eren. He is descending a ramp on his skateboard. Count on him moving at a speed of 0.8 m/s2. He's accelerating at this rate, but how much force is required? In the force equation, substitute the appropriate values to obtain the solution:
F = m × a = 50 kg x 0.8 m 2 = 40 kg x m 2, or 40 N.
