1 Answer. Steve J. The only force on it is its weight, w=9800N .

∴F=(2kg)×(3ms2). ∴F=6kgms2=6 Newton. =6N. Therefore, Force required to accelerate the body is 6N.

ANSWER: 2,800 force is needed to accelerate a 1400kg car 2m.

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=Fm. 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.

A newton is the SI unit of force. An unbalanced force of 1 N will accelerate a mass of 1 kg at 1 m/s2. One Newton of force is equal to one kilogram-meter per second per second (1kg-m/s2).

Inanimate objects such as walls can push and pull. Determine the accelerations that result when a 12-N net force is applied to a 3-kg object and then to a 6-kg object. A 3-kg object experiences an acceleration of 4 m/s/s.

here, m=1000kg and a=3m/s2 . hence, the force needed to accelerate the 1000kg car by 3m/s2 is 3000N .

Formula of Net Force FN is the force acting on a body. When the body is at rest, the net force formula is given by, FNet = Fa + Fg.

Net force is the vector sum of forces acting on a particle or body. The net force is a single force that replaces the effect of the original forces on the particle’s motion. It gives the particle the same acceleration as all those actual forces together as described by Newton’s second law of motion.

When several forces act on a system it is the net, external force that matters. The SI unit of force is the newton , named after the English physicist and mathematician Isaac Newton (1642–1727).

The weight of an object equals the mass of the object multiplied by the acceleration of gravity. Multiply the two values together. In order to find the normal force, you need to multiply the weight of the object by the cosine of the angle of incline.

A “net force” is an English phrasing for the sum of all forces. While there are multiple 100N forces being applied, the sum of the forces (or the “net force” on the block) is zero, so it remains at rest.

If two individual forces are of equal magnitude and opposite direction, then the forces are said to be balanced. An object is said to be acted upon by an unbalanced force only when there is an individual force that is not being balanced by a force of equal magnitude and in the opposite direction.

If you kick a football and it moves from one place to another, it means that unbalanced forces are acting upon it. Ball moves from one place to another after kicking it. This is an example of unbalanced force.

in case of book lying on the table its weight is balanced by the normal force exerted by the table. So, balance force is acting on it.
