What is a force?
A push or a pull
This is a measure of how fast something moves through a distance in a given amount of time.
What is speed?
What is a change in direction called?
acceleration
This law explains why when you kick a soccer ball it goes flying and you feel the force on your foot in the opposite direction.
What is Newton's Third law of motion?
What is the unit for force?
Newtons (N)
What is Newton's First Law of Motion?
What is if an object is at rest it will stay at rest, if an object is in motion it will stay in motion until acted upon by an unbalanced force.
A force that slows down objects when they rub against each other
What is friction?
What is a change in the speed of an object considered?
ACCELERATION
What is Newton's Third Law of Motion?
the Law of Motion that states for every action there is an equal and opposite reaction....
Who discovered the laws of motion?
Who is Isaac Newton?
A change in position
What is motion?
True/False:
Action and reaction forces (Newton's 3rd law) are ALWAYS equal in size and opposite in direction.
True
What is the net force?
What is 0 Newtons?
Newton's First Law of Motion states that an objects...
motion will remain constant unless acted upon by an outside force.
What happens if there is no force acting upon an object?
It will continue to move at the same speed in the same direction.
An object's resistance to any change in motion
What is inertia?
50 N right and 60 N left will result in.
10 N left
A change in a moving object's speed or direction is..
What is Acceleration?
Interpret the graph below?
This is the force that pulls things to the center of the earth.
What is gravity?
A golf ball rolls down a hill on the golf course. Which statement best describes how friction affects the motion of the golf ball?
A. Friction causes the golf ball to roll forwards and backwards.
B. Friction decreases how far the ball rolls.
C. Friction increases how fast the ball rolls.
D. Friction causes the ball to bounce.
B. Friction decreases how far the ball rolls.
What is constant speed?
1.When the speed of an object stays the same.
2.When the speed of an object increases.
3.When the speed of an object decreases.
1.When the speed of an object stays the same
How will this object move?
What object will move to the right?
You and your dad are moving the couch from one side to another. Your dad pushes with a force of 35 N to the right and you push with a force of 25 N right. What is the net force on the couch?
60 N right
Causes an object to start or stop moving, accelerate or change direction.
Unbalanced Force
