What 2 things change when an unbalanced force is applied to an object?
When the forces on an object are unbalanced the changes that could happen are the object speeds up, or slows down. And it can changes direction.
What 2 things affect the acceleration of an object?
-- the object's mass -- the net force acting on it
What two things should you describe about a force that acts on an object?
the 2 things you should describe about a force that acts on an object is the size and direction
What is the definition of unblanced forces?
Balanced forces are forces that are balanced and there is no change in motion. Unblanced forces are the opposite of a balanced force. that means that unbalanced forces are not balanced and there is a change in motion.
What 2 things need to occur for work to happen?
A force has to to be exerted for a distance
What two things happen to an object when placed under a microscope?
Actually, there are three things: 1. object magnifies (zoom) 2. flips 3. and invert (from the <--- to the --->)
What if forced are not in balanced?
If the forces on an object are not balanced then it could do one of a number of things - 1. change speed (accelerate or decelerate) 2. change direction 3. change shape 4. spin if the forces on an object are balanced then it will stay in its original direction at a steady speed (this could be zero ie stationary)
What 2 things change when an unbalanced force is applied to an object?
When the forces on an object are unbalanced the changes that could happen are the object speeds up, or slows down. And it can changes direction.
What 3 things must happen to be able to see something?
1. there mush be a source of light 2.the light must strike an object 3.the light must be reflected from the object to your eye
What happens when a balanced pair of forces acts on a single object?
When all forces are balanced, the object is either stationairy or moving in one direction inTekkit - Episode 2 a constant speed
How can you tell if a force is balanced or unbalanced by looking at it?
2 Forces are unbalanced when an object that is not moving starts moving or changes speed or direction. Balanced forces are the opposite they are where an object that is not moving stays still or an object that is moving stays at a constant pace.
What 2 things affect the acceleration of an object?
-- the object's mass -- the net force acting on it
Air pressure exerted equally on an object from different directions is what 1. balanced pressure 2. gravitational pressure 3. fluid pressure 4. constant pressure?
1. balanced pressure
What two things should you describe about a force that acts on an object?
the 2 things you should describe about a force that acts on an object is the size and direction
What are the ratings and certificates for Casualty - 1986 These Things Happen 2-15?

The weight of a 1.2 kg object of charge Q is just balanced by another object of equal but opposite charge fixed to a support 102 cm above it What is the magnitude of the charge Q in microC?
Since weight is balanced by charge, set weight (mg) equal to Coulomb force (F) mg = k [(Q^2)/(r^2)]
What are 2 things stems do for plants?
keeps the plant balanced and it takes in water for the photosynthesis process to make food
