Mechanics Flashcards
1
Q
How do you find gradient of a curve
A
Gradient if a tangent
2
Q
What is area under velocity time graph
A
Distance travelled
3
Q
What type of shape will a projectile make
A
Parabola
4
Q
Does acceleration of a falling object depend on mass?
A
No they accelerate at the same rate due to gravity
5
Q
Describe terminal velocity
A
Falling object will accelerate towards the ground. It’s velocity will increase as it falls but so does the drag forces acting on the object due to air resistance. Eventually the drag= weight meaning no over all force. No more acceleration
6
Q
If an object is in equilibrium it means…
A
It is stationary or moving at constant velocity
