How does law of interaction apply to road safety?
Newtons law of Interaction applies to driving when a car hits a wall the wall will also hits the car. When both cars crashed they will experience equal and opposite forces and they also have identical time of impact.
How does the law of inertia influence a person who is driving how does it affect their motion?
According to inertia, an object will not change its course or speed unless acted upon by a counteracting force. An object will remain at rest unless acted upon by an outside force. An object in motion will remain in motion unless acted upon by an outside force.

How are the principles of inertia applied to a car?
A driver must apply the brakes to compensate for the intertia gravity creates as a car goes downhill. The second proviso to the principle of inertia is that no force acts on the moving object, but many forces act on a car when it is driven.
How is the law of physics related to road safety?
If you were driving a car 65 mph on a freeway for 40 miles, you will undoubtedly use more gasoline than if you were to drive at the same speed for the same distance in a truck. Newton’s third law tells us that when you push against something it pushes back on you with an equal and opposite force. It is the law of action and reaction.
How does Newton’s first law of inertia affect us?
Newton’s Law of Inertia: Newton’s first law tells us that an object in motion stays in motion, and an object at rest stays at rest unless acted upon a net force. The first law of motion affects us when we are in a moving vehicle because, no matter how fast the car is moving, we will be moving that fast also.
How are Newtons laws related to car safety devices?
By increasing the impact time, the force on the occupants is dramatically reduced, because of this ÃÂcushioningÃÂ effect. Newton’s first law (a body will continue its state of motion unless acted upon by a non-zero net force) is another law that explains how crumple zones work in the face of an accident.
What is the effect of inertia on driving?
Effect of Inertia on Driving While driving, inertia keeps your vehicle moving unless the vehicle is acted upon by something, such as your brakes, the road surface, a fixed object (such as a tree), or another vehicle. Inertia also causes your body and loose objects in the car to keep moving forward if your vehicle comes to a sudden stop.
How is inertia related to vehicle occupant safety?
Getting your head around the idea of inertia is necessary to understand vehicle-occupant safety. If you were to collide with an object while traveling at 40mph, your car would abruptly stop, but according to inertia, your body would continue moving forward at 40mph until another force stops it.
If you were driving a car 65 mph on a freeway for 40 miles, you will undoubtedly use more gasoline than if you were to drive at the same speed for the same distance in a truck. Newton’s third law tells us that when you push against something it pushes back on you with an equal and opposite force. It is the law of action and reaction.
How is Newton’s law of inertia related to physics?
Newton’s Law of Inertia: Newton’s first law tells us that an object in motion stays in motion, and an object at rest stays at rest unless acted upon a net force Inertia is the tendency to resist the change in motion.
