Newtons Laws of Motion

let a Body moving with initial velocity 'u' changes its velocity to 'v' in time 't'

then ,

acceleration 'a' = (v-u)/t

=> a * t = v - u

=> a * t + u = v

=> v = u + a * t

Well, I can't give you any pictures but I can give you a simple definition that is very easy to understand.

Newton's Laws of Motion

Law 1- (often referred to as the law of inertia) An object at rest will tend to stay at rest and an object in motion will continue to move at the same velocity (speed in a certain direction) until acted upon by an unbalanced force.

Hope this helped.

Friction originates from the fact that everything is rough at a small enough scale. When these rough parts grind against each other, something must move out of the way, since every force results in motion. When something does give, part of the force is used, and since the scale is so small, heat is created as individual molecules move.

The work done by the coolie is zero because the force he exerts is in the vertical direction (lifting the load against gravity) while the displacement is in the horizontal direction. Work is only done when the force and displacement are in the same direction.

No, dropping two objects of different mass from the same height doesn't contradict Newton's 2nd Law. The law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass, so objects of different mass will experience different accelerations due to gravity even when dropped from the same height.

m/s^2 ? , strictly speaking this should be (m/s)/s , meaning velocity change per second, so if you go from 0 to 10 m/s in 2 seconds , your acceleration is

10/2 = 5 (m/s)/s

maybe m/s^2 is easier to type ?

To recap, Newton's first law states that an object in motion will stay in motion with constant velocity given that there are no net forces acting upon it. For example, if a ball was pushed with zero net forces acting on it besides the first force push, it will go on forever until a force decides to act on it, such as friction or gravity. Contrary to Newton's first law, Newton's second law implies that if an object is acted upon with existing net force, the object will accelerate with the same direction.

The equation Force (F) = mass (m) x acceleration (a) derives from the second law. Similarly to the first law, any net force on a body is conserved, implying the rule of conservation of momentum. In the first law, a force acted on a body will cause the body to move with the same magnitude of force in the same direction if there is zero net force. In the second law, a net force on a body causes the body to accelerate with the same direction as the net force.

If the raindrop is falling at a constant speed, then it has reached terminal velocity. This happens when the downward force (due to gravity) is the same as the upward force due to friction. As such the net force acting on the rain drop is 0.

Yes, it is possible for a nonzero net force to act on an object without changing its speed. This can happen if the force is acting perpendicular to the direction of motion, resulting in a change in direction but not speed (as in circular motion).

Rugby players in motion tend to stay in motion unless acted upon by an external force—a concept known as Newton's First Law of Motion. When a player is running and suddenly stops or changes direction, they experience the impact of an external force that affects their motion. Similarly, when a rugby player tackles another player, they apply a force to alter the opponent's motion according to Newton's First Law.

The net force on the car can be calculated using Newton's second law, F = m * a, where F is the net force, m is the mass of the car (1200 kg), and a is the acceleration (20 m/s^2). Therefore, the net force on the car would be 24,000 N.

Yes, Newton's first law can be deduced from his second law. Newton's first law states that an object in motion stays in motion, and an object at rest stays at rest, unless acted upon by an external force. When applying the second law (F=ma) to an object with no external forces acting on it (F=0), we find that the acceleration (a) is zero, which means the object continues in its current state of motion, as described by the first law.

Strictly speaking, you would say that a force acts on a system and the impulse of that force corresponds to the change in momentum of the system due to the action of the force. More mathematically, the impulse of a force is defined as the integral of that force with respect to time over the time period that the force acts.

The unit of measurement commonly used for calculating ship total resistance is Newtons (N). Total resistance is the sum of different types of resistance a ship faces while in motion, such as wave-making resistance, viscous resistance, and appendage resistance.

A large truck typically has more inertia than a small car because inertia is directly proportional to an object's mass. The greater mass of the truck means it will resist changes in its state of motion more than the smaller car.

A catapult demonstrates Newton's second law of motion by showing how the acceleration of the projectile (object being launched) is directly proportional to the force applied by the tension in the catapult's arm (F=ma). This means that the larger the force applied to the arm, the greater the acceleration of the projectile, leading to a more powerful launch.

If there is no air resistance moving the 2000-kg box would cost virtually no effort since the slightest shove would set it into motion which it would continue indefinably.

Pushing the 1-kg box would require a constant investment of effort because you need to combat the force of friction.

Thus, pushing the 1-kg box around is more tiresome.

The reasons are the same as they are for any similar oscillatory system. It is largely because energy is dissipated as heat wherever there is friction: at the ends of the strings and where the balls collide. Hence the total amount of energy within the system falls until the oscillation is no more. Wherever there are resistive forces, there can be no perpetual motion without violating the Conservation of Energy principle.

Yes of course. The gravity is the one responsible for keeping the satellite in place. But hold your horse how can that be possible. If the gravity was the only force acting then the satellite should start moving in a spiral fashion thereby crashing down on the earth surface. Here we see the action of something called the centrifugal force which is one of the famous pseudo forces.

Now what is a pseudo force? Well these are the forces which does not exist in reality. It is something which you assume to exist to counter balance the other force that is keeping you spinning called the centripetal force(like gravity in case of satellites). Even you feel this force like when you're standing inside a bus and the bus takes a sharp turn and you tilt the other way.

You can experience weightlessness by taking a parabolic flight, where the plane rapidly ascends and descends to create short periods of simulated zero gravity. Another option is to visit an astronaut training center where they offer zero-gravity simulators. Lastly, space tourism companies like SpaceX and Blue Origin are developing commercial trips to space where passengers can experience weightlessness.

both will have same kinetic energy ,so forward velocity will be lower for bowling ball , the time to go up then down to the ground under gravity will be the same for both, so distance = velocity * time , so lighter (golf)ball will travel further because its velocity is higher

second thoughts,

assume launch angle same for both, ball with greater launch velocity will travel further. (laws of ballistics)

if work done on ball (f * d) is same on both , the lighter ball will have greater launch velocity, though both will have same kinetic energy at launch

taking one cylinder , area of bore * length of stroke gives displacement (or volume) of one cylinder , then * number of cylinders = total engine displacement

for rough power calculation you can research the equation

The force produces an acceleration of 0.5 m/s^2 on a body of mass 1 kg, so using Newton's second law (F=ma), the force is 1 * 0.5 = 0.5 N. When the same force acts on a body of mass 2 kg, the acceleration will be 0.5 N / 2 kg = 0.25 m/s^2.
