When you lift a box off the ground gravity opposes your lifting force true or false?
Well, it's true that the gravitational force acting on the box acts in the direction
opposite to the direction of your lifting force, but there's nothing malicious or
contrary about it. In fact, the gravitational force was there before you came on
the scene, and as you lined up your lift, it was you who decided to oppose it.
What else can I help you with?
True or false an object that is dropped will hit the ground before an object that is thrown horizontally from the same height?
False, provided the drop occurs no sooner than the throw, and the ground is flat .
Lifting a piano into a truck is an example of doing work?
False
Is lifting free weights is a form of isotonic exercise?
false
Lifting free weights is a form of isotonic exercise?
false
Lifting a piano into a truck is an example of doing negative work?
False
The horizontal speed of a projectile launched over flat ground will affect the time that the projectile will stay in the air is this true or false?
this is false. the horizontal speed of the object has absolutely nothing to do with how long it takes to fall. if you fire a bullet on level ground it will hit the ground at the same time an apple would if you drop it from the same distance above the ground at the same time. the force of gravity is the same on everything on earth.
Gravity on the moon is twice bigger then gravity on earth?
False. Gravity on the moon is 1/6 that of Earth.
What is a false statement about hair?
One false statement about root-hairs is that they can sense gravity. It is a common misconception that gravity effects the direction of growth.
Is it true or false when a crumpled piece of paper falls to the ground more quickly than a flat piece of paper becauseof gravity?
False, the gravity on the sheet of paper is the same regardless of its shape. However the crumpled sheet has less air resistance than the flat sheet allowing it to fall faster.
Gravity gives you your mass true or false?
False. You will have the same mass on our moon, but weigh 1/6th as much as on the Earth.
True or false In outer space there is no gravity?
False. While gravity is weaker in outer space compared to that on Earth, it still exists. Gravity is what keeps objects in orbit around planets and stars, and even affects the interactions between celestial bodies in the universe.
What is a false statement about regarding root-hairs?
One false statement about root-hairs is that they can sense gravity. It is a common misconception that gravity effects the direction of growth.
