TRUE OR FALSE. when an object changed direction without changing its speed, it is not accelerating

Physics
1 answer:
tatyana61 [14]3 years ago
3 0

Answer:

True.

Explanation:

The velocity vector is constant in magnitude but changing in direction. Because the speed is constant for such a motion, many students have the misconception that there is no acceleration. ... But the fact is that an accelerating object is an object that is changing its velocity.

Two identical carts-A and B-initially are moving on frictionless air tracks. The initial speed of cart A is twice that of cart B
rodikova [14]

Answer:

b) non-zero and the same as the change m momentum of cart B

Explanation:

As we know that change in momentum is also known as impulse which is equal to the product of force and time interval

so we will have

\Delta P = F\Delta t

since we applied same force on two carts for small time interval of t = 1 s

so the impulse is given as

\Delta P = F(1)

so both the carts will have same change in momentum as we know that force and time interval is same for both

so correct answer is given as

b) non-zero and the same as the change m momentum of cart B
