Kinematics

The kinetic energy of the vehicle when it is travelling faster is four times as great. It the brakes apply the same retardation and the friction from the tires on the road surface is unchanged then the stopping time will be four times as long.

If an x-t graph is a position-time graph, velocity is the slope of the line on the graph.

Assuming no air resistance, the speed of a ball increases by the same amount it decreased when going up due to gravity. This means the ball gains the same speed returning to its original point as it lost when it was thrown upwards.

At 60 mph you are traveling at 88 feet per second.

An x-t graph shows displacement over time, and a v-t graph shows velocity over time. The combination of the two graphs can give you great detail about the motion of an object over a given period of time. For example, if an object moved 2 cm over 2 seconds on the x-t graph, that says nothing about what direction the object moved in, but if you combine that data with the v-t graph and see that over those 2 seconds the object had a positive acceleration, that means that the object was moving away from the origin of the graph.

potential energy changes to kinetic energy

60 mph = 88 feet per second

50 mph = 50/60 times 88 = 73.33 feet per second

The momentum-time graph is the integral of the force-time graph. that is, it is the area under the curve of the f-t graph.

Four times as farther.

The coaster have a large amount of potential energy when it gain height, kinetic energy when it gain speed instead.

Just draw the two diagonals of the rectangle,the point of intersection you will get5,is the centre of gravityof rectangle

Yes. A single gas particle experiences gravitational force.

I don't know what is astronamy wise but in the dog world it is the registration for a champion agility dog. My dog's dad has that regestration and one for obedience which is OMCH his name is Karastar Blackjack. He is either #1 or #2 obedience dog in the country! My pup looks so much like him it isn't even funny!

1 mile = 5280 feet 1 hour = 3600 seconds So, 55 mph = 55*5280 feet per hour = 55*5280/3600 feet per second = 80.66... fps

OK. You're holding a brick, and you're lowering it very slowly and gently to the floor.

Because of gravitational forces acting on the brick, it wants to accelerate downward

at 9.8 m/s-sq, but you're not letting it fall.

In order to do that, you have to exert an upward force on the brick, and you have to

maintain that upward force on it as it settles all the way down. You're exerting a force

that points up, through a distance that points down. Your muscles do negative work,

meaning that they absorb mechanical energy. That's the potential energy that the brick

gives up on its way down.

(You almost had me there. It's a great question, and I had to think about it. That was

an uncomfortable feeling.)

Not very accurate, but I hope you can get the idea.

Most battery manufacturers provide such graphics on their Web sites.

Six miles per second is the same as 21,600 miles per hour or 34,760 kilometers per hour.

For an electric buzzer, it's electrical energy.

There is no drag in a vacuum to act against the acceleration.

How can you compute your calories burned? Let's try an example. Say you weigh 150 pounds and you are walking for one hour at a rate of 3.5 miles per hour. Multiply 150 pounds by .035 = 5.25 calories burned per minute. Therefore, you would burn 315 calories during your one hour walk (5.25 times 60 miuntes). However, if you walk at a rate of 4.5 miles per hour, you will burn 7.2 calories per minute and 432 calories per hour. But you will have walked further (4.5 miles) than you walked with the 3.5 mph pace and, therefore, will burn more calories.

60 km/sec is the same as 1 km/minute, that is, 1 km every 60 seconds.

It will take 7 hours and 20 minutes.
