Newtons Laws of Motion

In an isolated system where no external forces are acting, momentum is conserved during the interval of collision. This means the total momentum of the objects before the collision is equal to the total momentum of the objects after the collision.

an example can be anything that's not moving like a skateboard, a bike a soccer ball, and a lot more. hope this helps

Up and down are directions based on relative position.

On Earth, up is the general area "above" a specified point. It is also the direction you are moving in when you oppose the force of gravity, such as when you "stand up."

Down, similarly, is the area "bellow" a specified point, and is also the direction you move in when you fall.

Of course, in an environment that is devoid of gravity, up and down are relative to a persons physical orientation. Up being above the individual in question, and down being below.

if a gun recoil kinetic energy (ke) is same as bullet kinetic energy then :

say 0.02 kilogram slug @ 1 000 m/s the ke 0.5*m*v^2 = 10 000 joules (j)

say gun @ 1 kg then : 10 000 j = 1 * v^2 , then v = sq root 10 000 = 100 m/s

actually, last line should read:

say gun @ 1kg then : 10 000 j = (1 * v^2)/2, then v=sq root 20 000=141m/s

Increasing the velocity of the roller coaster can make it more thrilling by creating stronger g-forces and faster changes in direction, leading to greater sensation of speed and excitement for the riders. Additionally, varying the velocity throughout the course with sudden accelerations and decelerations can add unpredictability and intensity to the ride experience.

To change the motion from anticlockwise to counterclockwise, you can simply reverse the direction of rotation. This can usually be achieved by adjusting the settings or controls of the object or equipment that is rotating, such as a motor or a fan. Alternatively, you could physically modify the object itself to rotate in the opposite direction.

The first law of motion is also known as Newton's law of inertia. It states that an object at rest will remain at rest, and an object in motion will remain in motion with a constant velocity unless acted upon by an external force.

If a parachute canopy is too big, it may lead to a slower descent rate, which could increase the risk of drifting off course due to wind. It may also reduce the precision and control during landing, potentially leading to a harder impact.

The man must pull with a force equal to his weight plus the weight of the basket, which is 95 kg * 9.8 m/s^2 ≈ 931 N. Since he is rising with constant velocity, this force must also counteract the force of gravity pulling him down.

Forces acting in opposite directions combine by subtracting the smaller force from the larger force to determine the net force.

Yes--because of Newton's first law, the passenger wishes to stay in its constant state of motion, which is standing still in this case. Hence, when the train starts to move forward, the passenger will want to stay at the point he/she was and will fall backwards.

You mean a force I guess. A force acting on an object will make it accelerate or decelerate, and if it is acting at an angle to the existing line of motion will make it change direction.

Newton's first law of motion is discovered by Isaac newton himself (otherwise he won't be associated with the law)

To calculate the mechanical advantage of a compound machine, you need to know the input force applied to the machine and the output force obtained from the machine. Additionally, you will need to understand how the individual simple machines within the compound machine are connected or arranged to determine the total mechanical advantage.

A magnet attracts another object due to its magnetic field, which is a force that pulls certain materials towards it. This attraction occurs because of the alignment and movement of the magnetic domains within the magnet and the object, creating a magnetic force between the two.

The force applied by a machine to overcome resistance due to gravity or friction is known as the applied force. Applied force is the amount of force needed to move an object against a resisting force, such as the force of gravity or friction. This force is usually measured in Newtons (N).

• When an object is stationary, the applied force is equal to the resisting force.
• When an object is moving, the applied force must be greater than the resisting force in order to maintain the object's motion.
• If the applied force is too small, the object will slow down and eventually stop.
• If the applied force is too great, the object may accelerate or move too quickly.

In order to determine the applied force, the resisting force must first be calculated. This can be done by multiplying the mass of the object by the acceleration due to gravity. The resisting force due to friction can be calculated by multiplying the normal force of the object by the coefficient of friction between the object and the surface it is in contact with.

The acceleration a of a body is parallel and directly proportional to the net force F acting on the body, is in the direction of the net force, and is inversely proportional to the mass m of the body, i.e., F = ma.

Newton's first law of motion states that an object at rest will remain at rest and an object moving at a constant velocity will keep moving at that velocity unless an external force acts on it. This is sometimes called the law of inertia.

Friction will reduce when you try to get rid of it. But understand that it is impossible to eliminate friction. A world without friction would not function. The wheels on a car would spin in place, without going anywhere. If you tried to take a step forward, you would fall over, and then be unable to get up. Friction is what makes the world operate when it comes to transportation. --AN AP PHYSICS STUDENT

Acceleration is the rate at which an object changes its velocity. It can be calculated by dividing the change in velocity by the time taken for that change to occur. Acceleration can be in the same direction as the velocity (speeding up) or in the opposite direction (slowing down).

It will depend upon the initial velocity of the body. If 'u' be the initial velocity of the body, then the final velocity will be:

v = u + at (v = final velocity, a = acceleration, t = time)

i.e., v=u+10*7 = (u + 70) m/sec.

If u=0 (i.e the initial velocity be zero) then final velocity, v=70 m/sec.

Newton's first law is sometimes called the law of inertia. Whether you call it that or not, the first law basically defines the characteristic of inertia.

The law is stated in various ways, but one way is like this.

A body at rest will remain at rest or a body in motion will continue in a straight line with the same velocity unless acted on by an external force.

That is the law. The second law says what happens of you have an external force.

The point is, that the first law introduced the idea that inertia is a natural state of being and an inherent law of nature. There is no magic, things don't spontaneously move around for no cause.
