Car with a mass of 1100 kg is moving with a velocity of 30m's due east what is its momentum?
Momentum = (mass) x (velocity) = (1,100) x (30) = 33,000kg-m/sec due east
How can the velocity of an object change if the speed doesn't?
Easy answer: velocity is defined as speed in a specific direction. So, if a car is traveling at a velocity of due west, 60 miles per hour, then turns onto a road going north, the velocity has changed to due north, 60 miles per hour. But the speed has stayed the same.
How is friction harmful when driving a car?
Friction slows down a car. As such, in order to maintain the velocity of the car, energy, i.e. gasoline, is required due to friction.If there were no friction, an impossible state, the car would require no energy to maintain its velocity once it had achieved the desired velocity.
When you are describing the rate that a race car goes around a track should you use the term speed or velocity to describe the motion?
Since velocity is speed with direction, you would use speed in reference to average rate of change of position, since the direction keeps changing. You can use velocity in reference to instantaneous speed, since a car is going in a specific direction at each instant in time.Examples:80 km/h is a speed.80 km/h due north is a velocity.
Which of these objects has the most mechanical kinetic energy a spring compressed a rock sitting on a cliff a bycicle going 10mph a car going 60 mph?
Kinetic energy is energy available due to velocity, so you can exclude the compressed spring and the rock sitting on a cliff. As far as the bicycle vs the car, the car is the easy winner. EK = 0.5 m v2 Since both the mass (m) and the velocity (v) of the car exceeds that of the bicycle, it is clear that EK-Car is much greater than EK-Bicycle.

What is the velocity of a car that traveled 300 km east in 2 hours?
150 km per hour due East (or even -150 km per hour due West).
Do speed and velocity have same meaning?
No. It's confusing unless you're into physics or mathematics but velocity is a vector quantity with speed is one aspect. Velocity includes speed and the direction of motion. A car is going 60 miles per hour as speed. A car is going 60 MPH due north is velocity.

What is the difference between an object's speed and an object's velocity?
Speed is a scalar quantity and thus a general term; if a car is traveling at 60 mph that is its speed;Velocity is a vector quantity that has speed and direction associated with it. If a car is traveling at 60 mph due east that is its velocity.The two terms are often used interchangeably.

One car travels due to east at 40km per h and a second car travels north at 40km per h are their velocities equal?
No. "Velocity" includes a magnitude and a direction. If any of the two are different, then the velocities are also different.
Is it possible that velocity of an object be in a direction other than the direction of acceleration?
Yes. Acceleration is change in motion. Velocity -- speed and a vector -- combined with mass provide momentum. While such directions are meaningless, imagine you are in space and there is (to get a picture and bearing of it) a 'north/south' direction and an 'east/west' direction. Suppose you were going due north at a constant 100 km/h (not accelerating), but you turned 90 degrees east and began accelerating in that direction at 1 km/s2. You are not suddenly travelling due east just because you are accelerating east, but are slowly arcing east of north as you continue the acceleration. In fact, to eventually go due east after starting off due north, you would actually have to steer a bit south of east and accelerate in that direction as simply accelerating due east after having been moving due north will make east an asymptote (a goal you can get close to but not quite reach). By steering and accelerating a bit south of east, the asymptote is along that vector and making due east eventually achievable.

What direction is right if you are going north?
If you are going or facing due north, then east is to your right.
A car is traveling with a constant velocity of 33 meters per second due east What is it's speed?
The car is traveling at a speed of 33 meters per second.
