Both objects will hit the ground at the same time

Answer:

they both will hit the surface of moon at same time

Explanation:

When a bowling ball and potato chips are dropped at the same time on surface of moon

then during the motion above the surface of moon they both will have only force of gravity due to moon

so we have

F = mg_{moon}

now the we can say that the acceleration of object on this surface is given as

a = \frac{F}{m}

a = \frac{mg_{moon}}{m}

a = g_{moon}

since this acceleration on both objects is independent of their mass

so we can say that they both will hit the surface of moon at same time

If the acceleration of an object is zero at some instant in time, what can be said about its velocity at that time? 1. It is neg
Mkey [24]

3. It is not changing at that time

Explanation:

If the acceleration of a body is zero at some instant in time, it implies that the velocity is not changing at that point in time. Velocity is the rate of change of displacement with time.

✓Acceleration and velocity shares a very close relationship.

✓ For a body to accelerate, the velocity must change. Acceleration is defined as the rate of change of velocity with time.

✓If at any point, a body moves with constant velocity i.e the velocity does not change with time, the acceleration becomes zero.

✓ For acceleration to occur, a body must change velocity.

Which of the following is a true statement about work?
Over [174]

Answer:

It measure the effort it takes for an object to move

Explanation:

Work done is the force applied to move a body through a particular distance.

It can also to be said to be a measure of the effort it takes for an object to move.

The unit of work done is in Joules.

 To find work done, we use the expression below:

       Work done  = Force x distance

Which is not a simple harmonic motion (S.H.M.) (a) Simple Pendulum (b) Projectile motion (c) None (d) Spring motion
Scrat [10]

Answer:

b) Projectile MOTION

Explanation:

SHM is periodic motion or to and fro motion of a particle about its mean position in a straight line

In this type of motion particle must be in straight line motion

So here we can say

a) Simple Pendulum : it is a straight line to and fro motion about mean position so it is a SHM

b) Projectile motion : it is a parabolic path in which object do not move to and fro about its mean position So it is not SHM

d) Spring Motion : it is a straight line to and fro motion so it is also a SHM

So correct answer will be

b) Projectile MOTION
