Q
Resultant force,mass and acceleration formula
A
Resultant force = mass x acceleration
2
Q
What is the formula for resultant force
A
F = m a
3
Q
What is the weight of an object acting on
A
The weight of an object is the force acting on it due to gravity.
4
Q
The terminal velocity…
A
The terminal velocity of an object is the velocity it eventually reaches when it is falling. The weight of the object is then equal to the frictional force on the object.
5
Q
What opposes the driving force of a vehicle?
A
Friction and air resistance
6
Q
What increases braking distance?
A
High speed, poor weather conditions, and poor vehicle maintenance all increase the braking
distance.
7
Q
