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?
50m/s What's the units?
m/s (meters/second)
Which line represents the faster object? Explain your answer.
The green line represents the faster object because its slope is steeper. (Or the green line represents the faster object because it travels a greater distance in less time.)
What is the unit for force?
Newtons (N)
What is a balanced force?
What is when 2 forces act on something but there is no movement.
A force that slows down objects when they rub against each other
What is friction?
The force that pulls objects towards the center of the Earth
What is gravity?
What is the velocity of a car that traveled a total of 75 km north in 1.5 hours?
50 km/hr
Who discovered the laws of motion?
Who is Isaac Newton?
his graph shows the motion of an object.
Which best describes the motion of the object?
a) it is at rest
b) it is moving at a constant speed
c) it is continually increasing its speed
d) it travels at constant speed and suddenly stops
d) it travels at constant speed and suddenly stops
These two things determine the amount of gravity between two objects.
What is the distance and mass of the objects?
What is the net force?
What is 0 Newtons?
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.
Newtons 3rd Law
What is the speed of a car that travels 30 miles in 5 minutes?
What is 6 miles per minute?
What is an unbalanced force?
What is when 2 forces act on an object and there is movement.
50 N right and 60 N left will result in.
10 N left
What is Newton's 1st Law?
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 outside force.
Interpret the graph below?
This is the force of attraction among all objects with mass
What is gravity?
What is the formula to calculate speed?
What is distance divided by time?
What is the following graph illustrating below?
What is an object is accelerating?
How will this object move?
What is it will move to the right?
If the 5th grade is playing tug of war in gym and no one is moving, is this a balanced or unbalanced force?
What is balanced force?
Causes an object to start or stop moving, accelerate or change direction.
Unbalanced Force
