What does car tend to do when rounding a curve?
Kinetic energy wants to keep the car going in a straight line.
What type of driveway? Was it a curving and could not see the car before rounding the curve? Is it straight; then why did you not see the car blocking the driveway before even getting into car and/or backing..
Roads, particularly those that are designed for high-speed travel, tend to be inclined with the bottom at the inside of the curve and the top of the incline at the outside of the curve. This is to help the driver counteract the momentum of the car, which will tend to push the car towards the outside of the curve. Momentum is the tendency of an object in motion to remain in motion on a straight line course unless acted upon by an outside force. Because the car is turning away from the straight line to follow the road, a force has to be applied to move the car from the straight line to the curve. Inclining the road helps provide this force - it helps turn the car by allowing gravity to pull the car down the incline and towards the center of the curve and counters the pull of the car towards the outside of the curve via momentum. This is why, when driving at higher speeds, you have to be careful about how quickly you try to turn your car. If you try to turn faster than you can overcome the momentum of the car, you will flip the car sideways and start rolling it.
Not necessarily.Speed is a scalar measurement that only measures magnitude.Velocity, on the other hand, is a vector measurement and adds the important distinction of a direction.A car rounding a curve may be going the same speed, but its velocity is constantly changing throughout the curve because its direction keeps changing.
Because of the rotation of the earth and the shape
Yes, they do.
A banked curve.
It tries to follow a straight path instead of the curved one. The man mistakenly perceives this as a force pulling him toward the outside of the curve.
No, the car will move along a tangent to the track where the driver has put the car in neutral.
