Newton's Second Law Quick Check for Connexus 10th grade physical science
(all answers are the first option for better reading, they weren't originally like this on the quick check)
what is the measure of the amount of matter in an object?
- mass 💗
- net force
- velocity
- newton
how much force in Newtons is required to accelerate a 5 kg bowling ball at 2 m/s2?
- 10 n 💗
- 2.5 n
- 3 n
- 7 n
which statement correctly applies to a car that changes its velocity over a period of time?
- a nonzero net force is acting on it 💗
- no net force is acting on it
- forces are acting on it
- the combination of all forces acting on it is zero
in each of three trials of an investigation, a single force is applied to a mobile. each time, the mobile acquires a different acceleration. the table shows the relationship between the acceleration and the acting force. [picture of said table] which phrase best describes a graph that would represent the relationship shown in the table?
- an upward-sloping line drawn on a graph with acceleration shown on the y-axis and force shown on the x-axis 💗
- a downward-sloping line drawn on a graph with acceleration shown on the x-axis and force shown on the y-axis
- a downward-sloping line drawn on a graph with acceleration shown on the y-axis and force shown on the x-axis
- an upward-sloping line drawn on a graph with acceleration shown on the x-axis and force shown on the y-axis
which statement describes the motion of an object when the net force is zero?
- the object is at rest 💗
- the object is speeding up
- the object changes direction
- the object is slowing down
hope this helps <3
i took this test on the 11th so some questions might be changed in the future, but these are correct as of 11/11/22
also i posted this as a reply on the wrong question 💀 sorry to the person i replied to if ur reading this-
