When a force F acts on a body of mass m, the acceleration produced in the body is a. If three equal forces F1,F2 and F3 which are related as F1=F2=F3=F act on the body as shown in the figure.
When a force F acts on a body of mass m the acceleration of particle becomes a?
When a force F acts on a particle of mass m, the acceleration of particle becomes a. Now if two forces of magnitude 3F and 4F acts on the particle simultaneously as shown in figure, then the acceleration of the particle is 4F 90° 3F.
When a force acts on a body of mass 100g the change in its velocity?
When a force acts on a body of mass 100g, the change in its velocity is 20 cm/s The magnitude of this – Brainly.in.
Under what condition is the acceleration produced in a body?
The acceleration produced by a force in the motion of a body depends only upon its mass .
When accelerating a body the resultant force exerted on it is equal to its?
The net force vector is equal to the mass of the body times the acceleration of the body. ——If a net external force acts on a body, the body accelerates. The direction of acceleration is the same as the direction of the net force. The net force vector is equal to the mass of the body times the acceleration of the body.
When a force F acts on a body?
Hint:Whenever a body is acted by some force it gets accelerated which in mathematical form it’s called Newton’s second law of motion as $F = ma$ here, we will find the net force acting on the body and its direction then will find the net acceleration of the body.
When a force F acts on a particle?
When a force F acts on a particle of mass m, the acceleration of particle becomes a . Now if two forces of magnitude 3F and 4F acts on the particle simultaneously as shown in figure, then the acceleration of the particle is 4F 90° 3F.
What is the velocity of a body of mass 100g?
Mass of body is 100 g . v = 20 m / sec . Thus the final velocity of body is 20 m / sec .
What is the change in momentum formula?
The impulse experienced by the object equals the change in momentum of the object. In equation form, F • t = m • Δ v. In a collision, objects experience an impulse; the impulse causes and is equal to the change in momentum.
How much acceleration is gained by a body of mass 2 kg when a force of hundred Newton acts on it?
250 m s−1 .
Under which condition can a body have zero acceleration?
Answer: Acceleration of a moving body can be zero when the velocity of the body is constant (that is, does not change) as acceleration is the change in velocity.
At what condition acceleration of a moving body is zero?
Acceleration of an object can be zero when it is moving with a constant velocity . Since velocity is constant, there will be no change in velocity and so there will be no acceleration. The above graph represents zero acceleration. Note: An object will accelerate if acceleration is in the same direction as velocity.
Can acceleration be produced without doing work give example?
Yes, it is possible that work done is zero even when a body is in accelerated motion. This happens when force is acting in a direction perpendicular to the direction of motion. For example, earth moving around the sun in a circular orbit under the gravitational force perpendicular to its path.
What are the forces that act on a body to change its state of motion?
The force responsible for changing the state of motion of objects in all these examples is the force of friction . It is the force of friction between the surface of the ball and the ground that brings the moving ball to rest.
What are the forces that act on the ball?
Answer: The forces are the weight, drag, and lift . Lift and drag are actually two components of a single aerodynamic force acting on the ball. Drag acts in a direction opposite to the motion, and lift acts perpendicular to the motion.
What is work done formula?
Mathematically, the concept of work done W equals the force f times the distance (d), that is W = f. d and if the force is exerted at an angle θ to the displacement, then work done is calculated as W = f . d cos θ .
