When you are sitting on a chair, the resultant force is?
In the absence of an external force, a moving object will
Move with a constant velocity
You are standing on a bus, facing forward, and you suddenly fall forward. You can imply that the bus's
Velocity is decreased
A constant net force acts on an object is inversely proportional to
If you exert a force F on an object, the force the object exerted on you will
Always be F
Mass and Weight
Are both two diffrent quantities
A packing crate slides down a ramp at a constant velocity. We can deduce
A frictional force is acting on it
A block of mass M slides down a frictionless plane inclined at an angle theta with the horizontal
The Normal force on the object is
An object sits on a frictionless surface. A 16 N force is applied to the object and it accelerates 2.0 m/s^2. What is the mass of the object?
If you push a 4.0kg mass object with the same force that you push a 10kg mass object from the rest
The 4.0kg mass accelerates faster than the 10kg object
What is the mass of an object on earth that has a weight of 250 N
An object has a mass of 60 kg on earth. What is the mass of the object on the surface of the moon where the acceleration due to gravity is 1/6 of that on earth?
Two forces act on a 5 kg mass. One is 8.0 N and is due north. The second is 6.0 N due east. What is the acceleration of the mass?
2.0 m/s^2 at 53 N of E
When the rocket engines of a spaceship are turned turned off while traveling in empty space, the spaceship will
Move with a constant speed
An object of mass m sits on a flat table. Gravity pulls down with a force equal to mg. What is the reaction force to this action force?
The table pushing up on the object with a force mg
