Kinematics

The gradient of an acceleration-time graph represents the rate at which the acceleration is changing over time. If the gradient is positive, it indicates an increase in acceleration, while a negative gradient indicates a decrease in acceleration. A horizontal line on the graph would represent a constant acceleration, where the gradient is zero.

106 kilometers per hour is equivalent to about 65.9 miles per hour.

The product of an object's mass and velocity is its momentum. Momentum is a vector quantity that describes the quantity of motion of an object and is given by the product of its mass and velocity.

At the top of the first hill, PE is at its maximum, whereas KE is zero. When the train starts to fall down the first hill, PE decreases and KE increases. At the bottom of the hill, KE is at its maximum, and PE is zero.

Well, yes; it is usually called "sound energy", but since it consists of movement of atoms, or pressure differences, it can also be considered a special kind of kinetic energy.

If the positive direction was defined at the outset as the direction opposite to the

direction in which the object happens to be moving just now, and the object is

slowing down, then the acceleration is positive because, algebraically, the object's

speed is increasing in the positive direction.

Sliding Kinetic Friction is usually greater than Rolling Kinetic Friction. Sliding Kinetic Friction is caused by two objects being dragged together, providing more opportunity for the objects' microscopic hills and valleys to catch.

Yes it is possible.

If a body goes round a circular path then distance covered by one full rotation will be 2 pi r

But the total displacement is 0.

Hence the average speed exists but average velocity does not exist.

On a pendulum, the greatest potential energy is at the highest point of the swing on either side, and the greatest kinetic energy is at the bottom of the swing.

On a roller coaster, the greatest potential energy is at the top of a hill, and the greatest kinetic energy is at the bottom of the hill.

Yes, robots can have kinetic energy when they are in motion. Kinetic energy is the energy possessed by an object due to its motion, so when a robot is moving, it possesses kinetic energy like any other object in motion.

The total potential energy of all microscopic particles in an object is due to the interatomic forces between them, which can be significant in solid and liquid states. The total kinetic energy of the particles is associated with their random motion, which increases with temperature. Both potential and kinetic energies contribute to the overall internal energy of the object.

To convert 5280 feet to miles, divide by 5280 to get 1 mile. Then, to find the speed in miles per hour, divide 1 mile by the time taken in hours (22 seconds converted to hours is 22/3600 = 0.00611 hours). Therefore, the speed is 1 mile / 0.00611 hours = 163.35 mph.

A speed vs. time graph could also be called a graph of acceleration. This graph will have a constant slope if the increase in speed is constant. It can also form a curved line if there is increasing or decreasing acceleration.

The total momentum before the collision is 80 kg * 70 km/hr + 120 kg * (-40 km/hr) = 5600 kgkm/hr - 4800 kgkm/hr = 800 kgkm/hr. The total mass after the collision is 80 kg + 120 kg = 200 kg. Therefore, their speed after the collision will be 800 kgkm/hr / 200 kg = 4 km/hr.

The kinetic energy of an object is directly proportional to its mass and also to the square of its velocity. This means that the higher the mass and the velocity of an object, the higher its kinetic energy will be. Therefore, doubling the mass of an object will double its kinetic energy, while doubling the velocity of an object will quadruple its kinetic energy.

Velocity of 4 meters per second??? I will assume so. ( need kilograms, so... 5 grams = 0.005 kilograms )

KE = 1/2mV2

KE = 1/2(0.005 kg)(4 m/s)2

= 0.04 Joules

The first match was believed to have started in ancient Greece, around the 8th century BC. It was probably a contest between two athletes in the city of Olympia during the Olympic Games.

Kinetic friction is the friction that applies when an object is moving; static friction is the friction that applies when the object is not moving.

Static friction must always be greater than, or equal to, kinetic friction.

211 mph is equivalent to approximately 339.57 km/h.

Kinetic energy. I learned this from Berkley charter school Florida. By my 5th grade teacher Mr.vliet.

Then your speed is precisely (70 miles per 200 minutes).

If you do the division of (70/200), you find the more familiar unit rate:

(70 miles / 200 minutes) = 0.35 mile/minute = 21 miles/hour .

The slope of a straight line on a position vs. time graph represents the object's velocity. A steeper slope indicates a faster velocity, while a shallower slope indicates a slower velocity. The slope can be positive for motion in the positive direction and negative for motion in the negative direction.

The increased damage when two bodies collide head-on is due to the momentum of the objects, which is the product of their mass and velocity. When two bodies collide from opposite directions, their momentums add up, resulting in a greater force of impact compared to collisions at other angles where momentums may partially cancel out.
