How much net force is required to keep a 2kg object moving to the right and with a constant velocity?
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.
What is the impulse momentum theorem?
The impulse-momentum theorem states that the impulse applied to an object will be equal to the change in its momentum.
What is the net force acting on a body of mass 2 kg moving with a constant velocity of 10 m s?
How does a 2kg body move under the action of a constant force?
Under the action of a force , a 2 kg body moves such that its position x as a function of time t is given by , x=t^2/3 , where x is in metre and t in seconds.
What is the formula for impulse-momentum theorem?
Momentum and Impulse The impulse of a force is I=Ft I = F t – when a constant force F acts for a time t . The units are Ns . The Impulse-Momentum Principle says I=mv−mu I = m v − m u which is final momentum – initial momentum so Impulse is the change in momentum.
What is the SI unit of impulse?
The SI unit of impulse is the newton second (N⋅s), and the dimensionally equivalent unit of momentum is the kilogram metre per second (kg⋅m/s).
What is the SI unit for momentum?
|kilogram meter per second (kg⋅m/s)
What is the net force of the body of an object with mass 2 kg moves with a uniform velocity of 10 m per second?
From the second law of motion, Force F=ma=2×10=20 N. Q.
What is the formula for net force mass?
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 is the formula for net force with weight?
Units of Force The equation Fnet=ma F net = m a is used to define net force in terms of mass, length, and time. As explained earlier, the SI unit of force is the newton. Since Fnet=ma, 1N=1kg⋅m/s2.
How much net force is required to keep 5 kg object moving rightward with constant velocity of 2m s?
The amount of net force required to keep a 5-kg object moving rightward with a constant velocity of 2 m/s is ____. Net force is always m•a. In this case, the velocity is constant so the acceleration is zero and the net force is zero.
What net force is required to keep a 500kg object moving with a constant velocity of 10m s?
Correct answer: A net force is only required to change an object’s motion. The 500 kg object is moving at a constant velocity; therefore, there is no net force (0 Newtons) acting on the object.
How much net force is required to keep an object moving at a constant velocity?
According to Newton’s first law of motion, any object moving at constant velocity has no net external force acting upon it, which means that the sum of the forces acting on the object must be zero.
How much net force does it take to keep an object moving at a constant velocity?
His First Law states that an object with a net force of zero acting on it will remain at rest, if initially at rest, or it will maintain a constant velocity.
