If these boys are pulling with the same amount of force. What will happen?
The boy in blue will win.
They will not move at all.
The boy in red will win.
_______________ is how fast an object changes over time.
speed
velocity
momentum
What is the formula for force?
F=M/A
F=A/M
F=M*A
What happens when two forces act in the same direction?
They cancel each other out.
The stronger one prevails.
Their strengths are added.
When you tell the direction and speed of an object, you give its
motion
velocity
acceleration

5 Newtons up
5 Newtons down
15 Newtons up
If a 10 kilogram object accelerates suddenly at 15 m/s2, how much force was applied to the object?
150 Newtons
15 Newtons
150 kilograms
A baseball is thrown a distance of 50 meters. What is the speed if it takes 2 seconds to cover that distance?
100 m/s2
25 m/s2
52 m/s2
Speed is equal to
Distance/Time
Time/Distance
Time x Distance
Speed is different from velocity because
Velocity has a direction
Speed uses Distance /Time
Velocity doesn't include time
What is the difference between mass and weight?
mass is how much matter is in an object, and weight is the gravitational pull on that object
mass and weight are the same
weight affects how much mass is in an object
What slows down the motion of an object or keeps it from starting?
mass
friction
gravity
What is motion?
Any change in an object or person's position
How fast an object goes
Motion is like acting
What pulls a ball back to earth?
Gas
Gravity

inertia
motion
gravity
Why does a crumpled piece of paper land before a flat sheet of paper?
Gravity exerts more force on the crumpled paper.
There is more air resistance on the flat paper.
