Question

The acceleration of an object is caused by:

A change in speed.
A change in velocity.
A change in direction.
An unbalanced force.

Answer 1

All of the above?

Answer 2

only one is the right answer

Answer 3

Change in velocity in thast csae

Answer 4

Change in velocity automatically includes all the others.

Answer 5

Acceleration is a change in velocity. Velocity is essentially a speed and direction. So by changing only the direction changes the velocity and change in speed changes velocity.

But what is an unbalanced force? That just means you have a net force. But F=ma is one of newton's law. Force is just an acceleration on a mass!

They are all correct!

Answer 6

got it

Answer 7

yes they all are correct, but if only one have to be chosen then i'll say change in velocity

Answer 8

Change n velocity automatically includes all the others.

Answer 9

The first 3 are alike, but the last one is separately not included as an unbalanced force.

Answer 10

What a terrible question.

Answer 11

yeah that's correct.....these questions make a student commit suicide !

Answer 12

Well i think last one will be the correct option. Because for any kind of acceleration net force is required. even to change the direct a net force is required. So it's a quite tricky question. Answer will be D
