Define "Force"
Two people are pushing on a box from opposite sides. They apply the same amount of force. Does the box move?
No
True or false: If an object is pushed with more force, it will move faster or have a greater acceleration.
True!
These are forces that change an objects motion.
Unbalanced forces
If a mass of 2 kg is accelerated to 5 m/s2, what is the force generated?
10 N
A feather and a bowling ball fall to the ground at different times due to what?
Air resistance
F = M * A
Force = Mass x Acceleration
What law is this?
What is Newton's Second Law of Motion
What do you call all of the combined forces acting on an object?
Net Force
A block with a mass of 50kg is pulled with a force of 100N. What will be the acceleration of the block?
2 m/s2
What is the measure of gravitational attraction or force?
What is Weight (Newtons)
When forces are acting on an object in opposite directions, they are _________________ to find net Force.
Subtracted
Mr. Fitz is going down the sidewalk on his skateboard. Mrs. Ashley decides to get on, too. What will Mr. Fitz have to do to keep the skateboard moving at the same speed?
Push with more force
Which of Newton's laws take force into consideration?
All of them!
Can objects with balanced forces still have motion?
Yes. The object can be still or moving at a constant speed.
An object goes from a stop to 60 m/s in 5 seconds and generates a force of 120 Newtons. What is its mass?
10 kg
The weight of a person on Earth is 490 Newtons. What is their mass?
50kg
