"Mass does not have a direct effect on the force needed to move an object."
True
False
Objects of ___________ mass have a greater acceleration when the same net force acts on them.
greater
smaller
equal
How much net force is needed to accelerate a 10 kg object with ? Just give the numerical answer without adding the unit N for Newton.
If you need 150 N to accelerate an object with , what is then the mass in kg of that object?
The state when an object is either at rest or moves with a constant velocity is called ".... equilibrium".
Newton's first law of motion is also called "The law of ...."
What is the fundamental unit of force?
kg . s / m^2
kg . s^2 / m
kg . m / s^2
None of the above
Which description states Newton's first law best?
An object at rest wants to stay at rest and an object in motion wants to stay in motion.
In an inertial reference frame, an object in translational equilibrium (a=0) will stay in this state unless a (non-zero) external force acts on it
An object in translational equilibrium (𝑎=0) will stay in this state
In an inertial reference frame, an object in translational equilibrium will stay in this state
In which of the following situation(s) is the net force equal to zero?
A ball is rolling on the table with constant velocity.
A ball is thrown in the air.
A car slows down.
You are sitting still in your chair.
