, The acceleration of an object is False
zero, then that object cannot be
moving. T/F
Two cars are traveling at the same False
constant speed v. Car A is moving
along a straight section of the road,
while car B is rounding a circular
turn. Both cars are accelerating?
Because of the t squared in the False
equation: Xf = Xi + Vit + 1/2 at²
the equation is valid if acceleration
changes
It is more difficult to start moving a True
heavy carton from rest than it is to
keep pushing it with constant
velocity
An object thrown horizontally from False
a tall building hits sooner than if
dropped.
The centers of a 13kg lead ball and Force of gravity = (Gm₁×m₂) divided by r²
a 70 g lead ball are separated by
0.14 m. What is the gravitational
force between them?
A ball is thrown vertically upward False
and then comes back down. During
