When walking down the street, the two main forces acting on you are gravity pulling you down towards the Earth and the normal force from the ground pushing you up. According to Newton's first law of motion, if the forces are balanced (in this case, gravity and the normal force), you will continue moving at a constant velocity in a straight line. If you want to change your motion (speed up, slow down, change direction), you would need to apply an additional force in the direction you want to move.
What one thing on earth makes newtons first law not seem to be true?
Friction is one thing on Earth that can make Newton's first law seem not to be true, as it can act as a force that opposes motion and can cause objects to stop rather than continue in a state of constant velocity.
How does newtons laws of motion apply to volcanoes?
Newton's laws of motion can be applied to volcanoes in various ways. For example, the first law states that an object at rest will remain at rest unless acted upon by an external force, which can be seen in the build-up of pressure within a volcano before an eruption. The second law relates to the acceleration of magma as it moves towards the surface during an eruption. The third law can be observed in the equal and opposite forces created during volcanic explosions.
What newtons law explains why a ball bounces?
when a ball is dropped it hits the floor and the ball is flattened. That creates energy. The only way the ball can release the energy is bouncing back up. But the ball starts to lose its height and the ball eventually loses its energy and comes to a stop.
What do it means when they say balanced forces?
When forces are balanced, the total force acting on an object is zero, resulting in no change in the object's motion. This means that the forces acting in opposite directions cancel each other out. As a result, the object either remains at rest or continues to move at a constant velocity.
Who was the Athenian councilor to first codify the law of Athens?
The Athenian councilor who is credited with first codifying the law of Athens is Draco. Draco was known for his harsh legal code, which was later replaced by Solon's more moderate laws.
The mass shouldn't make any difference in an ideal system.
Using v^2=u^2+2as for each object, you get v=sqrt(2gH) and sqrt(2gh) for the two objects. The ratio will simplify to sqrt(H/h).
Why do action reaction forces never cancel each other?
Because they are acting on different objects.
The action and reaction forces - in the sense of Newton's Third Law - act on different objects. In some everyday situations, such as a book lying on a table, pressing down on the table, and the table pressing up on the book, these forces are balanced by additional forces, in other cases, they are not.
Please note that "action" and "reaction" forces (from Newton's Third Law) act on different objects. Only forces acting on the same object may cancel out (for purposes of Newton's Second Law), if their vector sum happens to be zero.
How is the center of the gravity determined when an object is at rest or in motion?
If the object is a thin lamina with uniform thickness (e.g. a piece of paper), the the centre of gravity of the object is at its geometrical centre. It can be determined by suspending a load (e.g. pendulum) on an edge of the lamina twice and the point where the plumb lines intersect is the centre of gravity.
What is the force of a vehicle traveling 40 mph and hitting a stationary object?
I'm pretty sure that's going to depend on the vehicle's mass. I'm sitting here
performing a gedanken experiment right now, with a house fly and a Mercedes
both hitting the same brick wall.
To calculate the force required to pull the 5000kg pipe along the 10 sets of idle pipe conveyor systems, you need to consider the frictional force acting against the movement of the pipe. This frictional force will depend on the coefficient of friction between the pipe and the conveyor systems. You can use the formula F_friction = coefficient of friction * Normal force to calculate the force required. The force needed to overcome this frictional force should be less than the total normal force acting on the pipe.
No, if the car is moving at a constant velocity, there is no need to lean in any special way to compensate for its motion. Your body is also moving at the same constant velocity as the car, so you will not feel any effect of the motion.
One feels the effects of velocity in a moving vehicle when its motion changes, such as when the vehicle accelerates, decelerates, or changes direction. When a vehicle is moving uniformly, there are no noticeable changes in speed or direction, so the effects of velocity are not as perceptible.
How fast must a car accelerate if the force exerted on it is 2580n with a mass of 654 kg?
a = F/M = 2,580/654 = 3.945 meters/second2 . . . about 0.4 G
Why ball is in the law of inertia?
The ball remains at rest or in motion with a constant velocity unless acted upon by an external force. This is known as Newton's first law of motion, which is a fundamental principle in the law of inertia.
What can proceed in the opposite direction?
Traffic, a conveyor belt, a river current, and a moving walkway can proceed in the opposite direction.
What is the magnitude of net force acting on a drop of rain falling down with a constant speed?
consider a sphere moving through a viscous medium the fluid layer in contact with the sphere is moving with same velocity but the layer far away is at rest. This makes a relative motion to be setup.viscous force acts on this drop.The backward force is proportional to the speed of the drop.at a stage the viscous force balances the downward force.hence the body moves with a constant velocity called terminal velocity.
What are the fire pit laws in chelmsford ma?
In Chelmsford, MA, outdoor recreational fires are allowed as long as they comply with the town's regulations. These include having a permit for larger fires, keeping fires contained, using only clean, dry firewood, and ensuring that the fire is supervised at all times. It's recommended to check with the local fire department or town officials for specific information on fire pit laws in Chelmsford.
Newton's second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Therefore, a large massive body requires a larger force to change speed quickly because its mass increases the inertia that opposes the change in speed.
When does is an object at zero velocity only for an instant but its acceleration is not zero?
this case is observed when you throw a ball at a wall.the ball comes to momentary rest after after striking the wall.but it experiences a retarding force.at that time the retarding force is non zero,so acceleration is non zero.but velocity is zero.same is the case when you throw an object up into air.there is constant acceleration of 9.8m/s^2 but at the top of trajectory the velocity is zero.
Is thrust on the rocket in the absence of gravitational force of attraction constant?
Yes, the thrust on the rocket remains constant in the absence of gravitational force. Thrust is the force pushing the rocket forward, generated by the propulsion system. It is independent of gravitational force.
What is your weight on the moon if you weigh 330 newtons?
If that is your eath weight then you weigh 54.6-non the moon,
about 124.9-n on Mars, and about 834.2-n on Jupiter.
Is it true that the net force acting on an object is equal to the rate of change of its momentum?
Yes, that statement is a concise way of expressing Newton's second law of motion. The net force acting on an object is indeed equal to the rate of change of its momentum. This relationship helps explain how forces cause objects to accelerate or change direction.
Yes, a force acting perpendicular to a horizontal force on a body can cancel out the horizontal force if the two forces are equal in magnitude and opposite in direction. This is known as the equilibrium condition, where the net force acting on the body is zero.
How Kinetic Energy is related to Potential Energy?
Kinetic energy is the energy an object possesses due to its motion, whereas potential energy is the energy an object possesses due to its position or condition. The interplay between kinetic and potential energy is often seen in systems where one can be converted into the other, such as a swinging pendulum where potential energy is converted into kinetic energy and back again. Both forms of energy are essential in understanding the behavior and dynamics of physical systems.
