When an object is fired at a certan height/angle, the object will begin to fall towards the Earth under the force of gravity. However, due to the curvature of the Earth, it falls but will never hit the ground (it is in "orbit"). What kind of force is gr
Centripedal
1 of 9
What causes terminal velocity (the maximum speed at which an object can fall).
Air Resistance
2 of 9
Mass is the amount of ____ in an object?
Matter
3 of 9
Using Newton's first law: A moving object will ____ when acted upon two equal, oppisite forces
Travel at a constant speed
4 of 9
Under what circumstances will an object (in this case; a car) accelerate?
When the thrust force is greater than the friction force
5 of 9
When using a moment force (such as turning a spanner), what should I do to make the process require less force (energy) from myself?
Make the spanner longer
6 of 9
If Moment = Force x Distance, how far should a 30N weight be placed from the pivot, in order to balance a 50N weight 10m from the pivot?
