How much force is required to move a body of mass 5 kg with 10 m per second square?
Expert-Verified Answer A= V-U/T = 10-0/2= 5 M/S SQUARE.. NOW,, WE KNOW THAT FORCE= MASS×ACCELARATION= 5×5= 25 NEWTONS..
Does the velocity of the cart change as you change the amount of force applied?
Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity.
The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.
What is the kinetic energy of a 10 kg object moving at 5 ms?
The kinetic energy of the object is 125 J.
How much force is 1kg mass?

What is the SI unit of force?
The SI unit of force is the newton, symbol N. The base units relevant to force are: The metre, unit of length — symbol m. The kilogram, unit of mass — symbol kg. The second, unit of time — symbol s.
Is mass and force the same?
Force, mass and acceleration are everyday words but often used inaccurately. Force is a physical influence, which when applied to an object causes it to accelerate in the direction from which it was applied. Mass is the amount of matter in an object and is expressed in kilograms.
What is the formula for mass acceleration?
Summary. According to Newton’s second law of motion, the acceleration of an object equals the net force acting on it divided by its mass, or a = F m . This equation for acceleration can be used to calculate the acceleration of an object when its mass and the net force acting on it are known.
What is Newton’s 2 law?
Newton’s second law is a quantitative description of the changes that a force can produce on the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.
What is the law of velocity?
Velocity and Newton’s First Law of Motion The first law of motion states that a body will remain at rest, or continue at a constant velocity, unless a force is applied. Essentially, velocity is always constant in this law. At rest, velocity remains zero.
Does acceleration depend on the cart mass?
Acceleration Depends on Mass You would only have to exert a small force on the empty cart to accelerate it. However, when the cart is full, the same amount of force will not accelerate the cart as much as before.
Does velocity mean speed?
Why is it incorrect to use the terms speed and velocity interchangeably? The reason is simple. Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement.
How to calculate velocity?
Determine the object’s original velocity by dividing the time it took for the object to travel a given distance by the total distance. In the equation V = d/t, V is the velocity, d is the distance, and t is the time.
How to find momentum?
Step 1: List the mass and velocity of the object. Step 2: Convert any values into SI units (kg, m, s). Step 3: Multiply the mass and velocity of the object together to get the momentum of the object.
How much force is needed to lift an object with a mass of 10 kg on Earth?
At the surface of the earth the acceleration due to gravity is approximately 9.8 meters per second squared, so the force is F=10⋅9.8=98. The units here are kilogram-meters per second squared” or kg m/s2”, also known as a Newton (N), so F=98 N.
How much force is required to change velocity of a body of mass 10kg from 2m s to 6m s?
To find the force required to change the velocity of a body from 2 m/s to 6 m/s in 2 seconds, we can use Newton’s second law of motion, which states that force (F) is equal to the rate of change of momentum. So, the force required to change the velocity of the body from 2 m/s to 6 m/s in 2 seconds is 20 Newtons.
What is the net force acting on a body of mass 10 kg moving with a uniform?
As we know, F=mass of body×acceleration of body by Newton’s second law of motion. Therefore, force is zero.
What is a force of 10 n acts on a body of mass 2 kg for 1m distance?
W=FS=EK=12mv2=10×1=10J.
