Newtons Laws and Friction



A car skids on wet road and crashes into another car. Describe in detail what is happening using Newton's Laws and the three forms of friction.

The car was accelerating so fast that it couldn't stop in time so it crashed.

Rylan N said...

There wasnt enough friction to stop the car.

Gareth B said...

Friction is stopping the car. It is sliding friction.

Evan L said...

Well their is rolling friction from the wheels, Newtons 3rd law is in action because the cars stop because the force of the cars colliding it causes it to stop.

Rylan N said...

There was not enogh static friction to keep the car from drifting then rolling friction made it so you couldnt stop

The water on the road makes it slippery, so there was sliding friction. The tires were probably still rolling, so there war rolling friction. They were going really fast so they could not stop, but I don't know how to describe static friction.

The car was accelerating to fast that it did not have time to slow down or change direction.

Well Newton's first law, which I'm sure you all know, comes into play here because the car would've kept driving but it was acted upon by and outside force (Other car). The crash was probably pretty bad too because the cars friction might have been reduced my the water, meaning friction would've been less affective in slowing down the car.

The car was accelerating to fast so it couldn't slow down or change direction in enough time.

The two cars hit each other but the one that skids(car one) bounces off and spins away and eventually stops once it hits the guard rail on the other side of the rode. The car(car two) that it hits however hits it brakes on impact and does't move much. The forces that come into play here are rolling friction, sliding friction, and Newtons's first and second laws. The rolling friction when the second car rolls back a little bit but not much and when the first car hits it. Sliding friction when car one bounces off car two and hits the guard rail. Newtons first law applies to the first car and the third law applies to both cars but more likely the first car.

Because of the water, sliding friction comes into affect and rolling friction is still there because of the wheels

Leslie K said...

There was no sliding fiction here Griffin.

First of all, the three types of friction are static, rolling, and sliding. The force on one car was greater than the other, bringing in Newton's Third Law of Motion. Because the car was going really fast towards the other car, the car got damaged.

Leslie K said...

The first sentence should read The two cars hit each with so much force that car one bounces off car two.

Several cars were in a head on collusion. Two cars skid to a halt using friction when they made contact with each other. The other car though required more friction to slow it down and changes directions. It slid across the road due to sliding friction and eventually hit the guard rail. The two card that collided rolled back with rolling friction when they smashed into each other.

Katie N. said...

There was enough friction.

King of Everything except for the MINIONS said...

Because the road was full of water so it was sliding friction and then rolling friction was happening because the car couldn't stop and the wheels were still moving when the water was under the car and it was Newton's first law of motion

Ella T. said...

Not enough friction= Car crash.

the road was covered and wet so it was moving friction happening because the car couldn't stop and the wheels were still moving when the water was under the car and it was Newton's first law of motion :)

When the car was skidding on the wet road, that was sliding friction. When the car couldn't stop and the wheel were still going round and round, that was rolling friction. I'm not sure how static friction would be described.

Julia M said...

There wasn't enough friction to stop the two cars from hitting each other.

Sliding friction occurs when the cars wheels stop moving, but the car still moves because of the water. It is also sliding friction when one car hits another, and moves the car.

Jacob G said...

The first car skids on the wet road, and then into the fast moving car. The people in the cars have kinetic friction when their cars crash. The cars have sliding friction AND YEAH

Sophia S:) said...

The car is moving along which is rolling friction. It crashes into the other car, static friction. Then sliding friction takes place. But Newtons third law states for every action there is an equal an opposite reaction.

Cassie :D said...

First, the car slides on a wet road, into another moving car. When it hits the other car it will soon stop.

when the cars wheels stop moving sliding friction friction occurs. so it keeps moving your car.

Alysse S said...

When the cars hit and it used the 3rd law because when the car hit the Guard rail which made them bounce back.

Patrick H said...

Well their is rolling friction from the wheels, Newtons 3rd law is in action because the cars stop because the force of the cars colliding it causes it to stop.

Jacob L said...

the rolling friction with the skidding, sliding friction from the wheels, and Newton's Third Law to move each car backwards.

McKayla. M said...

The car was having sliding friction and the momentum of the car made it crash into another car, cause the car to crash.

AutumnP said...

The rolling friction with skidding, there was sliding friction from the wheels. Newtons 3rd law in motion, The cars moved back

Abbie N said...

There was slidding friction from the car when it slid on the wet road newtons third law ws used because it caused the other car to move when it crashed into it.
