## Which vehicle experiences the greater force of impact?

When two vehicles moving at the same rate of speed are involved in a collision, the **vehicle that weighs less will** take the greater impact; the larger and heavier the vehicle, the greater the energy and momentum.

## Which vehicle experiences the greater change in acceleration?

(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 the greater acceleration the truck or the car?

Which has the greater acceleration: the truck or the car? **The car has the** greater acceleration because it has the smaller mass.

## Which vehicle is pushed further and why?

Answer: (1) On collision, both the car and the truck experience the same force as action and reaction are equal. and mass of car is less than the mass of truck, therefore, acceleration of car is more than the acceleration of the truck. (4) Car is pushed farther than the truck, **because car is lighter than truck**.

## Which vehicle experiences the greater force of impact a car B truck C both D none?

Answer : (a) Both will experience same amount of force of impact by third law of motion. (b) Mass of truck is greater then mass of car and initial ad final velocity **of car ad truck** are same i.e., v ad 0 respectively, therefore it will experience greater force of impact.

## Which car experiences a greater change in momentum during the collision?

A hummer and **a VW Beetle** travelling at equal speeds have head-on collision. Which vehicle will experience the greatest change in momentum? Justify your answer. The Beetle would have the greatest change in momentum because this car has a lesser mass, causing it to travel at a faster velocity after the collision.

## What is the relationship between force and acceleration?

The relationship between force and acceleration can be described from Newton’s First Law. If the force applied to an object is increased, then the acceleration of that object also increases by the same factor. In short, **force equals mass times acceleration**.

## Which one will have more acceleration when you use the same force to push a truck and push a car?

If you use the same force to push a truck and push a car, **the car** will have more acceleration than the truck, because the car has less mass.

## When would a small car have the same amount of change in momentum as a large truck?

When would a small car have the same amount of momentum as a large truck? **When the speed of the car is much greater than the speed of the truck**.

## Which vehicle is pushed further?

(i) On collision, both the car and the **truck** experience the same force as action and reaction are equal. and mass of car is less than the mass of truck, therefore, acceleration of car is more than the acceleration of the truck. (iv) Car is pushed farther than the truck, because car is lighter than truck.
