Kinematics

Motion energy is the energy an object possesses due to its movement, while position energy is the potential energy an object has based on its position in a system. Motion energy is related to kinetic energy, while position energy is related to potential energy.

Since torque is a force, and as such has a direction, it is a vector.

well, the area under the curve between a time interval is equal to the distance traveled on that specific time interval. So one quantity is distance. As for another quantity, the answer would be velocity, but I think they may want a less obvious answer. A quantity out side of velocity could be instantaneous acceleration. This is given by the slope of the the tangent line to the velocity-time graph.
Hope this helps you answer your question. Though I think the most simple way to understanding why is to take a course of calculus.

A spring pulley system works by using a spring to provide tension on the pulley system. When a force is applied to the system, the spring stretches, storing potential energy. This potential energy is then released, helping to move the load connected to the pulley. The spring tension assists in lifting or lowering the load with less effort.

None, since there can be no conversion. A mile is a measure of length while a kilometre per hour is a measure of speed. The two measure different characteristics and, according to the most basic principles of dimensional analysis, any attempt at comparisons or conversions between the two are fundamentally flawed.

The time it takes to travel 61 km depends on the speed at which you are traveling. For example, if you are driving at a speed of 60 km/h, it would take you 1 hour to cover 60 km, and an additional 1 km would take 1 minute, totaling 61 minutes.

The product of velocity and time yields distance travelled if the velocity is constant for the time in question. If velocity is not constant, one must first calculate the average velocity over a given time period before multiplying it by the time involved.

Examples of vector energy include kinetic energy and momentum. Kinetic energy is the energy an object possesses due to its motion, and momentum is the product of an object's mass and velocity. Both of these quantities have direction and magnitude, making them vector quantities.

Just as it leaves the bat after being struck. From then on it will gradually slow down as the friction of the air around it slows it down.

Alternatively, it may have the most kinetic energy as it leave the hand of the pitcher when he is throwing a fast-ball or when leaves the hand of a fielder when he is throwing it to another player. It depends on what part of the game you are talking about.

acceleration is the change in speed in a certain amount of time

eg

a car goes from 4km/h to 10km/h in 3 seconds, what is its acceleration?

10km/h - 4km/h=6

6/3 secounds=2

acceleration is 2km/h

acceleration= change in speed/time

Kinetic energy is proportional to the square of the speed; use this fact to calculate the increase in speed (60% increase means an increase by a factor of 1.6). Momentum is proportional to the speed.

By the Law of Conservation of Momentum, the total momentum after the collision must be the same as the total momentum before the collision.

The movement of an object is compared with a reference point or frame of reference to determine its speed, velocity, and acceleration. This comparison helps to understand the object's motion relative to a fixed point or another moving object.

One way to show this would be to do the following experiment:

Take a coil spring and tie two pieces of string to each end of it. Then tie one of the strings to something with wheels... preferably something whose wheels have a locking mechanism (maybe an office chair, a wagon, a bike). Pull the wheeled object by the string along a flat, level surface at a constant speed and note the elongation of the spring. Now try locking the wheels and pulling the object again in the same manner ... as long as circumstances are "normal" (i.e., you're not doing this on a skating rink or a floor covered in oil or something), it should feel harder to pull the object with the wheels locked, and the spring should elongate more as you pull it.

If fact that the spring is elongating more when sliding demonstrates that there is a higher force of tension in the string pulling on it. The higher tension is caused by greater drag in the chair, which is in turn caused by sliding friction. Voila!

The average slingshot can shoot projectiles at speeds of around 100-200 feet per second (30-60 meters per second). This typically translates to a maximum range of 100-200 yards (90-180 meters) depending on the design and quality of the slingshot.

25 waves are produced in 20 seconds , so

25 ÷ 20 = 1.25 waves in 1 second ...

so the Frequency is 1.25 Hz

1). one hour's progress during a motor trip

2). velocity of the car

3). acceleration of the car when the brakes are applied

4). gravitational force on a ball hanging from a string

5). force pulling a rolling ball down a ramp

6). lift on an airplane wing

7). drag on an airplane wing

8). torque on a wing-nut while tightening it

9). power radiated from Channel-2's TV transmitter

10). tension in bridge-support cables

Velocity = Displacement/Time =10.55m/11.31s = 0.932m/s

Value of constant velocity is 0.932m/s.

A scalar quantity is a physical quantity that has only a magnitude (size or amount) without any specific direction. Examples include mass, temperature, and speed. Scalars are typically represented by a single numerical value.

A changing slope on a velocity-time graph indicates that the object's acceleration is changing. If the slope is increasing, the acceleration is positive, and if the slope is decreasing, the acceleration is negative. A flat slope indicates constant velocity.

In the UK, speed limits are typically measured in miles per hour (mph). However, some signs may also display speed limits in kilometers per hour (kph) to cater to international drivers.

9 kilometers per hour is equivalent to approximately 5.59 miles per hour.

To convert knots to inches per second, use the conversion factor of 1 knot = 1.68781 inches per second. Multiply the speed in knots by this conversion factor to get the equivalent speed in inches per second.

Friction reduce the velocity, hence, it affect kinetic energy. The potential energy from static pressure is then drawn to maintain the velocity (transformation of potential -> kinetic energy). We then see the friction reduce the static pressure but actually, it affect kinetic first.
