Mass of the truck is greater than that of the car. Thus, the truck will experience a greater change in momentum as compared to the car. d. According to Newton’s third law of motion, for every action, there is an equal and opposite reaction which acts on different bodies.

## Which vehicle experiences the greater change in acceleration A car B truck C both D none?

(b) Since, both truck and car are moving with the same magnitude of velocity v, momentum change for both vehicles is same. (c) Mass and acceleration are inversely proportional to each other. Therefore, **car** experiences greater acceleration due to its smaller mass.

## Which has a greater change in momentum?

The momentum change is dependent upon the velocity change; **the object with the greatest velocity change** has the greatest momentum change.

## Which experiences the greater impact force?

**The faster you drive**, the greater the impact or striking power of your vehicle. The laws of physics determine that the force of impact increases with the square of the increase in speed. So, if you double the speed of a car, you increase its force of impact four times.

## Why do cars suffer more damage than the truck?

The car is likely to suffer more damage than the truck, as **it is lighter**. The acceleration i.e. change in velocity per second of car is more than that of the truck.

## Which vehicle experiences the greater change in momentum a car B truck C both D None 20.2 which vehicle experiences the greater change in acceleration A car B truck C both D None 20.3 which vehicle is likely to suffer more damage and why a car?

since the mass of the **truck is greater than** that of the car, it will experience a greater force of impact. Mass of the truck is greater than that of the car. Thus, the truck will experience a greater change in momentum as compared to the car.

## Which vehicle experiences the greater change in acceleration?

Which vehicle experiences greater acceleration greater? **The Honda** experiences greater de-acceleration because it has less mass. Newton’s 2^{nd} law (F=ma) can be rewritten to read a=F/m. For the same force the acceleration is inversely proportional to the mass.

## Which car has the greater change in momentum explain your answer?

Which car has the greater change in momentum? Explain your answer. **The car with higher mass and have the higher velocity will** have a greater change in momentum.

## What happens if one of the cars collided with more force than the other one?

Forces between two colliding objects

It doesn’t matter if one car is heavier (more massive) than the other. **The push force from one car will equal the push force from the other**.

## Which Cart (# 1 or #2 has the greatest acceleration?

Which cart (#1 or #2) has the greatest acceleration? Explain. **Cart #2** has the greatest acceleration. Recall that acceleration depends on force and mass.

## Is momentum always conserved?

**Momentum is always conserved**, regardless of collision type. Mass is conserved regardless of collision type as well, but the mass may be deformed by an inelastic collision, resulting in the two original masses being stuck together.

## What is change in momentum called?

This change in momentum is called **impulse**, and it describes the quantity that we just saw: the force times the time interval it acts over. The greater the impulse, the greater the change in momentum.

## What decreases negative effects to a driver in a crash?

Modern vehicles have features that reduce the forces on your body during a crash by **absorbing energy and increasing the distance** over which the impact occurs. These include: Crush zones, or areas of the vehicle designed to absorb impact by collapsing without harming the passenger area of the vehicle.

## Which car undergoes the greater change in motion?

Which vehicle undergoes the greater change in its motion, and why? — same force on each; **bike** undergoes greater change in motion because of its much smaller mass 58.

## What are the three factors that determine force of impact?

Three factors that determine force of impact are **speed, weight, and distance**. If a vehicle increases its speed from 20 mph to 60 mph its stopping distance will increase by 9 times.
