Newtons Laws of Motion

Newtons second law applies two bicycling because when your bike is going down hill, and you don't have to petal, your bike will not change direction unless you physically change the direction.

Both balanced force and net force refer to the overall force acting on an object. Balanced force occurs when the total force is equal in magnitude and opposite in direction, resulting in no change in an object's motion. Net force is the overall force that remains after all forces acting on an object are combined, determining its acceleration or deceleration.

YES. Infact, an object can have infinitely different moment of inertias. It all depends on the axis about which it it rotating.

You can allow an object to rotate about any axis (this may or may not pass through the object).

Nah, brah. Momentum and kinetic energy are conserved, but velocity is not. Correct me if I am wrong but from how I interpret this, any collision cause the colliding bodies to change their direction. Thus velocity, which is a vector quantitiy containing direction, is by definition changed in an elastic collision. I guess speed, which is the magnitude of the velocity, can be considered as being conserved?

Newton's First Law of Motion states that an object in motion stays in motion unless acted upon by an external force. In the case of car accidents, the force of impact can cause unbuckled passengers to continue moving forward with the same speed as the vehicle before the collision, leading to serious injuries or even death. Buckling up helps prevent this by providing a restraining force that keeps passengers safely in place during sudden stops or accidents.

To calculate distance with velocity and weight, you can use the equation for work: Work = Force x Distance. The force can be calculated by multiplying the weight with gravity. Velocity can then be used to determine the time it takes for the object to travel that distance using the equation Distance = Velocity x Time.

yes, a fan is an example of a circular motion

The first law of motion, also known as the law of inertia, states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by an external force. In the case of an ice skater sliding across the ice at a constant velocity, the skater will continue moving at that constant velocity unless a force (like friction or wind resistance) acts to change their motion.

Headrests help guard against neck injuries by providing support to the head and upper body during an impact, reducing the risk of whiplash. The headrest acts as a barrier that restrains the head's backward movement and helps maintain proper alignment with the spine, preventing excessive strain on the neck muscles and ligaments.

In Newton's second law of motion, force is defined as the product of an object's mass and acceleration. It is represented by the formula F = ma, where F is the force, m is the mass of the object, and a is the acceleration. This law describes how the acceleration of an object is directly proportional to the net force acting on it.

Objects at rest will not accelerate unless a force acts on them. This concept is similar to Newton's First Law of Motion, which states that an object will remain at rest or in uniform motion unless acted upon by an external force. Both ideas emphasize the need for a force to cause a change in an object's motion.

Yes. Consider an object with no torques acting on it (therefore the sum of the torques is obviously zero) but with a force directed through its center of mass.

How about a freely spinning wheel on a shaft? Would have to be in a vacuum.

Ok wait, the answer is yes. Consider a horizontal beam attached at one end that is 6 ft long. If a force (x) is applied at the end of it in the downward direction and another force is applied that is twice as powerful (2x) in the upward direction 3 ft from the attached end the net torque is zero but the net force is x in the upward direction.

F= M*g*Us

or

(Force needed) = (Mass of object) * (Gravitational field strength)* (Coefficient of Static Friction)

F (N)= .2 (kg) * 9.8 (m/s^2) * .4 (no units)

Solve it yourself

Static

When an object is moving on a rough surface, the frictional force acting on it is given by the equation F=μN, where μ is the coefficient of friction and N is the normal force. In this case, the frictional force is proportional to the mass of the object (m) and the acceleration (a) it experiences, so F=ma can be used to calculate the frictional force.

When an object is in equilibrium, the acceleration is zero. When the acceleration is zero, the velocity does not change; the non changing velocity includes the case when the velocity has value zero.

The first law of Newton, also known as the law of inertia, applies to tennis in that an object at rest (such as a tennis ball) will stay at rest until acted upon by an external force (such as being hit by a racket). Similarly, once the ball is in motion, it will continue moving in a straight line unless another force acts upon it, like the net or the ground.

To find the acceleration, use the formula F = ma, where F is the net force, m is the mass of the box, and a is the acceleration. Rearranging the formula to solve for acceleration gives a = F/m. Plugging in the values, a = 8.5 N / 24.3 kg = 0.35 m/s^2.

You can find acceleration by dividing the force applied to an object by the mass of the object. The equation is: acceleration = force / mass. This relationship is described by Newton's second law of motion.

Weight = Mass * Acceleration of gravity.

Weight = force of gravity on particular object.

Weight = force of gravity on an object;

Gravity = attracts all objects toward each other

Gravity is indeed a force, but only one out of many.

magnetic, frictional, mechanical ... .

When an ordinary force applied to an object, (me pushing my wheelbarrow) this would not be considered as being affected by gravity.

If the net force acting on an object is 0 N, the object will continue to move at a constant velocity in a straight line according to Newton's First Law of Motion.
