Physics of a car

Where is the force?

Friction travels in the opposite direction of motion.

Physics of driving a car

Our topics are breaking distance,positive/negitive accleration, centripetal force and friction.

The greater the velocity the longer it will take to come to a complete stop.

As the ball travels away from the starting point at the bottom of the ramp it creates negative acceleration.

As the ball rols down the hill it gradually increases in acceleration .

Positive acceleration- Accelerating force in an upward direction, such as from bottom to top, or from seat to head,the acceleration in the direction that this force is applied

Negative acceleration - Is a decrease in velocity with respect to time, The object can slow down (20m/s to 10m/s) or slow down(-20m/ to -10 m/s. Also Negative Acceleration refers to an object whose speed decreases as it moves away from its original starting position.

Breaking distance is the distance the vechicle travels fromt the point of applying the breaks and coming to a compelete stop.

As the truck applys the breaks it takes it 12 meters to come to a complete stop while going at a velocity of 10 MPH.

Centripital force is the force that pulls toward the center of the curve.

the force is driven toward the center point as the object moves in a circle along the outside.

as the lawn mower moves foward,the friction moves in the opposite direction

friction is the resistance to relative motion
