Newtons second law
How can newtons second law be represented mathematically
F=ma, A=f/m, M=f/a
An unbalanced force causes
something to accelerate
True or false: mass resists acceleration
true
what unit is acceleration measured in
m/s2
what is the acceleration of an object traveling at a constant velocity
0 m/s^2
Why would one ball accelerate more than the other when pushed with the same amount of force?
Different masses
Balanced forces cause no acceleration
True
mass is measured in what unit
kg
what can be measured by acceleration
How much an object slows down, how much an object speeds up, an object's change in direction
what are the appropriate units to describe acceleration
m/s^2
Why would one ball travel a greater distance than the other when pushed with the same amount of force?
Different masses
Force is measured with what unit
N
Football A has a greater mass than football B. which football will have greater acceleration when both are thrown with the same force in the same direction
Football A
The rate at which an objects velocity changes is called what
acceleration
what is an unbalanced force? Two objects where...
one has more force than another
If you push the ping pong ball & the basketball with the same amount of force, which one will go a greater distance?
The ping pong ball
your dogs wagging tail knocks over something over the cup of pencils sitting on your desk what kind of force is his tail
unbalanced force
What is mass?
a measure of the amount of matter in an object
If a hockey stick acts on a resting puck, what will happen?
the hockey stick will change the speed of the puck and make it accelerate
what is a balanced force? Two objects where...
They both have equal force
Will it take more force to push an empty shopping cart or a shopping cart that is full?
The full shopping cart
Net force is?
the sum total and direction of all forces acting on the object
If the mass is large how will it affect the gravitational force
The greater the size of the masses, the greater the size of the gravitational force
Suppose that the acceleration of an object is zero. Does this mean that there are no forces acting on it?
No, it means that the forces acting on it are balanced and the net force is zero
"if we apply a ______ to an object, its _____ will change and it will _______"
force, velocity, accelerate
