The dog pulled with a great amount of force therefore
the acceleration is less
the acceleration is more
the mass increased
the mass decreased
using the same force on different objects with different masses, the object with less mass
will accelerate quicker
will accelerate slower
will not move
will accelerate at the same speed
If the net force is equal to zero, the forces acting on the object are
balanced
unbalanced

What is a formula for force?
F = mc
F = ma
F = mb
F = m
In the force formula,
m = mass
a = acceleration
m= mass and a = acceleration
m = mass and b = breadth

10 m/s^2
.1 m/s^2
100 m/s^2
1 m/s^2
