Forces and Terminal Velocity
Cards in this deck (5)
- 1The faster an object moves through a fluid the greater the ___________ which acts on itFrictional force.
- 2An object falling through a fluid will initially accelerate due to the _________ . Eventually the resultant force will be 0 and the object will move at its _________ .Force of Gravity
Terminal Velocity (steady speed) - 3Why does the use of a parachute reduce the parachutist's terminal velocity?They experience more air resistance,
Frictional forces such as air resistance, friction and drag act against the direction of motion, so tend to slow the object down. - 4How can frictional forces be reduced?By streamlining the object or lubricating certain parts.
- 5What is the equation for Weight?Weight = Mass x Gravitational Field Strenght
W = m x g
