Force (in newtons) is equal to the mass of the object (in kilograms) multiplied by the acceleration of the object (in meters per second per second).

F = ma

F = 0.04 x 20

F = 0.8 newtons

The force required to accelerate a 70 kg object at a rate of 4.2 m/s^2 can be calculated using Newton's second law: Force = mass x acceleration. Plugging in the values, the force required would be 294 N.

I'm assuming you mean 4.2 m/s^2, as m/s is a measure of velocity

F=m*a

F=70kg*4.2m/s^2

F=294N

Force equals the mass in kg times the acceleration in m/s2. F = ma = 0.40kg x 20.0m/s2 = 0.8N

What does changing the mass of an object do the the force of an object?

Changing the mass of an object does not directly affect the force acting on it. However, according to Newton's second law (F = ma), increasing the mass of an object will require a larger force to accelerate it at the same rate. Similarly, decreasing the mass of an object will require less force to accelerate it.


Acceleration of a falling object is caused by the force of?

Acceleration of a falling object is caused by the force of gravity. Gravity is a force that pulls objects towards the center of the Earth, causing them to accelerate downward at a rate of 9.8 m/s^2.


If the mass of an object does not change a constant net force on the object produces a constant what?

If the mass of an object does not change, a constant net force applied to the object will produce a constant acceleration according to Newton's Second Law (F=ma). This means that the object will continue to accelerate at a constant rate as long as the force is applied.


What are Velocity and Force?

Velocity is the rate of change of an object's position over time, indicating both its speed and direction of motion. Force is any interaction that can cause an object to be pushed or pulled, accelerating it or changing its shape. Force is typically described by its magnitude, direction, and point of application.


What does Newton SI unit of force mean?

The Newton is the SI unit of force, defined as the amount of force required to accelerate a one kilogram mass by one meter per second squared. This unit is commonly used to measure the strength of a force acting on an object.

What force is necessary to accelerate a 70-kg object at a rate of 4.2 ms?

Force = mass x acceleration = 70 x 4.2 = 294 Newtons


The force that is needed to move somethimg is proportional to what?

The force needed to accelerate an object at some rate is proportional to the object's mass.The object may be moved by as small a force as you want. It just won't accelerate at a very high rate.


How is the rate of motion of an object affected by an increase in force applied?

An increase in applied force will cause the object to accelerate.


What is needed to make an object accelerate?

To make an object accelerate, a force needs to be applied to the object. This force can come from various sources such as gravity, friction, or propulsion. The magnitude and direction of the force will determine the rate at which the object accelerates.


What force is necessary to accelerate a 70 kilogram object at a rate of 4.2 m's?

The force needed to accelerate a 70 kg object at a rate of 4.2 m/s^2 would be 294 Newtons (N). This can be calculated using the formula F = m*a, where F is the force, m is the mass, and a is the acceleration.


What is required to accelerate an object?

To accelerate an object, a force must be applied to it in the direction of the desired acceleration. The amount of force required is determined by the mass of the object and the desired rate of acceleration, as described by Newton's second law of motion, F = ma.


What is the rate an object accelerate depends on?

The rate at which an object accelerates depends on the magnitude of the applied force and the mass of the object. Newton's second law of motion states that acceleration is directly proportional to the net force acting on an object and inversely proportional to its mass.


The downward force acting on an object in free fall is the force of?

gravity. This force causes the object to accelerate towards the Earth at a rate of approximately 9.8 m/s^2.


What happenes to the force when the mass increases?

When the mass increases, the force required to accelerate the object also increases according to Newton's second law of motion, F = ma. This means that a greater force is needed to accelerate a heavier object at the same rate as a lighter object.


What force is necessary to accelerate at 70kg object at a rate of 4.2 minutes per seconds?

To accelerate a 70kg object at a rate of 4.2 m/s^2, you would need a force of 294 Newtons. This is calculated using Newton's second law, F = m*a, where F is the force, m is the mass of the object (70kg), and a is the acceleration (4.2 m/s^2).


What is the effect of force in an object?

Force applied to an object can cause it to accelerate, decelerate, or change direction. The magnitude and direction of the force determine the resulting motion of the object according to Newton's laws of motion.


What force is necessary to accelerate a 70 kg object at a rate of 4.2 ms squared?

The force required to accelerate a 70 kg object at a rate of 4.2 m/s^2 is 294 N. This can be calculated using Newton's second law, F = m x a, where F is the force, m is the mass (70 kg), and a is the acceleration (4.2 m/s^2).
