What is the force acting upon a projectile?
gravity
What is the only force acting upon a projectile?
gravity
Which is the only active force a projectile is any moving object upon?
Gravity
What is projectile velocity?
Velocity is the time rate of change of displacement of an object. Velocity is the distance travelled in unit time in a stated direction. It is a vector quantity since it gives us both magnitude and direction.
In the absence of air friction does the horizontal component of a projectile's velocity change as the projectile moves is this True False?
A projectile will travel on a straight line unless external forces act upon it. Gravity will pull the projectile downward, i.e. affect its vertical velocity component. This is why the projectile will decelerate upwards, reach a maximum elevation, and accelerate back down to earth. The force vector of air resistance points in the opposite direction of motion, slowing the projectile down. For example, If the projectile is going forward and up, air resistance is pushing it backwards (horizontal component) and down (vertical component). Without air resistance, there is no external force acting upon the horizontal velocity component and the projectiles ground speed will stay constant as it gains altitude and falls back down to earth.
What is the difference between magnets and electromagnets?
A magnet exerts magnetic force when 'at rest', or when it is not acted upon by any other force. An electromagnet exerts magnetic force only when energized by electricity, and is normally constructed from a ferrite core wrapped by an electric coil.
How do you find force using pascal?
Pascals are a unit of pressure. pressure = Force / area being acted on. Therefore: Force = Pressure x Area being acted upon.
Is an object sliding along a horizontal table an example of projectile motion?
No. The definition of projectile motion is an object dropped launched into the air, which is acted upon by gravity. (For the basic forms of the motion, air resistance is ignored.)
What is applied force?
it is the force acting upon an object
What is cumulative force?
cumultive force is the force that acts upon a specific object
How do you chose winding coil gauge of transformer?
