Forces of varying types, when they are imposed and caused an unbalanced state to an object, always result in acceleration.
True
False
What will happen to the acceleration of an object if the mass is doubled?
halved
tripled
remains the same
becomes zero
Acceleration and mass are inversely related.
True
False
Newton unit comes from the combined units of mass and weight.
True
False
What does direct proportionality mean?
When one factor increases, the other factor also increases.
When one factor increases, the other factor decreases.
When one factor increases, the other factor remains the same.
When one factor increases, the value of the other factor becomes zero.
An object accelerates to 5 m/s2 from rest in 2.5 seconds. What is its initial velocity?
5 m/s
2.5 m/s
0 m/s
10 m/s
Unbalanced forces result to
change in speed
change in direction
acceleration
all of these
The direction of the net force is _______ proportional to acceleration.
inversely
directly
equally
none of these
The lower the net force acting on the object, the more it accelerates.
True
False
Which of the following is true about the second law of motion?
The rate of change of momentum of a body over time is directly proportional to the force applied, and occurs in the same direction as the applied force
An object at rest will stay at rest, and an object in motion will stay in motion unless acted on by a net external force.
All forces between two objects exist in equal magnitude and opposite direction
none of these
