Forces and the Laws of Motion. Forces. Force is a push or pull on an object. Unit for force: N or Newton. Balanced forces Where there are two forces that counteract each other and result in no movement (EQUAL) Unbalanced forces One force is greater than the other force. (UNEQUAL).
N or Newton.
One force is greater than the other force.
Answer = _50__ newtons
How much force is needed to accelerate a
500.0 kg car at a rate of 4 000 m/s/s?
A 100 N force causes an object to accelerate at
2 m/s/s. What is the mass of the object?
A 1.5 kg ball is kicked with a force of 450 N.
What acceleration did the ball receive?
Laws of motion Interactives
Motion of a falling object after being
given an initial forward velocity
Combination of initial vertical force
and downward force of gravity
Causes object to follow a curved path
Gravity and Weight
Mass – measure of amount of inertia
Weight – force of gravity pulling on an object
Weight is product of mass and acceleration due to gravity ( 9.8 m/s/s)
W = mg
W- weight in newtons
m- mass in kilograms
g- acceleration due to gravity in meters per second squared
