Force
A push or pull that one body exerts on another.
What is Force?
Formula for speed.
What is s=d/t?
A change in velocity.
What is Acceleration?
Acceleration due to gravity.
What is 9.80 m/s2?
An object at rest will remain at rest and an object in motion will continue moving at a constant velocity unless acted upon by a net force.
What is Newton's First Law?
Force acting on an object that are opposite in direction and equal in size.
What is Balanced Forces?
Speed with a direction.
What is Velocity?
The measure of acceleration.
What is m/s2?
Formula for free fall.
What is 9.80 m/s2 =(vf-vi)/t?
When one object exerts a force on a second object, the second object exerts an equal but opposite force on the first.
What is Newton's Third Law?
Unbalanced forces that are not opposite and equal.
What is Net Force?
Has number value and direction.
What is Vector?
Formula of acceleration.
What is a=vf-vi/t?
A pumpkin dropped off from a building after 6.5 seconds.
What is v=64 m/s?
The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
What is Newton's Second Law?
Tendency of an object to resist any change in its motion.
What is Inertia?
Ratio of distance to time.
What is Speed?
A motorcycle traveling at 25 m/s speeds up to 13 m/s in 17 seconds. Show the acceleration.
What is a=-0.7 m/s2?
A nuclear bomb dropped on a test site after 14 seconds.
What is v=137 m/s?
Newton's Second Law equation.
What is Force=mass times acceleration?
One force is applying 40 N to the right and another force is applying 170 N to the left. Show the net force.
What is 130 N?
A plane travels 75 kilometers in 2.4 seconds, then slows down to 45 kilometers in 1.6 seconds. Show the average speed.
What is s=30 km/s?
A straight downward slope.
What is slowing down or negative constant acceleration?
A piece of paper dropped on the floor after 5.76 seconds.
What is v=56 m/s?
1.A rocket blasting off into space.
2.Using seat belts.
3.Two people of the same mass pushing against each other, both of them don't move.
