How much net force is required for a 2 kg object moving horizontally with a speed of 4m s?

How much net force is required for a 2 kg object moving horizontally with a speed of 4m s?

Answer and Explanation: Thus, if an object is moving with constant velocity and no external force, like a frictional force, then the object continues to move with the same velocity in the same direction. Hence the net force required is ZERO.

How much net force is required to keep a 2kg object moving to the right and with a constant velocity?

Answer: AC If an object is moving at a constant speed in a constant rightward direction, then the acceleration is zero and the net force must be zero.

Is true or false once the object hits the water the forces are balanced and the object will stop?

False. Once the box hits the water, the forces are balanced (50 N down and 50 N up). However, an object in motion (such as the box) will continue in motion at the same speed and in the same direction. When the box strikes the water, it stops accelerating; yet it does not stop moving.

What two variables is acceleration dependent on?

The second law states that the acceleration of an object is dependent upon two variables – the net force acting upon the object and the mass of the object.

How much force is required to accelerate a 2kg mass at 3 ms?

Force (F)= Mass (m)× Acceleration (a). ∴F=ma. ∴F=(2kg)×(3ms2). ∴F=6kgms2=6 Newton.

What is the formula for the net force of a moving object?

Net force is the sum of all forces acting on an object. The net force can be calculated using Newton’s second law, which states that F = ma, where: F is the net force. m is the mass of the object.

What is an object of mass 2kg is moving with a velocity of 10im s?

Answer. To find the momentum of the body, we can use the formula: momentum = mass × velocity. So, the momentum of the object would be 2 kg × 10 m/s = 20 kg·m/s.

How much net force is required to accelerate a 1000kg car at 4m s 2?

So the net force is required to accelerate a 1000 kg car at 4.00 m/s2 is 4000 N.

How much force is required to move 1kg 1m s?

One Newton is the force required to accelerate one kilogram of mass at 1 meter per second per second.

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.

What is the sum of all forces called?

Net force. The combination or the resultant of all the forces acting on an object is called Net Force, which is basically the sum of all the forces acting on that object.

What does newton’s 2nd law predict?

Newton’s second law of motion states that F = ma, or net force is equal to mass times acceleration. A larger net force acting on an object causes a larger acceleration, and objects with larger mass require more force to accelerate.

What does ∑ F stand for?

Mathematically, the second law is most often written as. 4.2Fnet=maorΣF=ma, where Fnet (or ∑F) is the net external force, m is the mass of the system, and a is the acceleration. Note that Fnet and ∑F are the same because the net external force is the sum of all the external forces acting on the system.

What is Newton’s 3rd law called?

Newton’s Third Law: Action & Reaction His third law states that for every action (force) in nature there is an equal and opposite reaction.

What is the 3rd Newton law?

Newton’s third law simply states that for every action there is an equal and opposite reaction. So, if object A acts a force upon object B, then object B will exert an opposite yet equal force upon object A.
