Category 1
This law of motion states that an object’s motion won’t change unless acted upon by a force.
Newton’s First Law
Pushing or pulling an object.
Force
This law of motion states that heavier objects need a larger force to make them move.
Newton’s Second Law
A position change when compared to another object.
Motion
This law of motion states that for every action there is an equal and opposite reaction.
Newton’s Third Law
A contact force resulting from two objects rubbing against each other.
Friction
Combination of all forces acting on an object.
Net Force
Unit used to measure force.
Newton
A place or object used for comparison to determine whether something is in motion.
Reference Point
A force that pulls objects toward each other as a result of their masses.
Gravity
You pull with 60 N forward, your friend pulls with 50 N forward, and friction resists with 30 N backward.
What is the Net Force?
80 N Forward
A situation where two or more forces acting on an object are equal in size but opposite in direction, resulting in a net force of zero.
Balanced Force
F=M x A
Which law uses this equation?
Newton’s Second Law
A force that causes a change in an object's motion. It occurs when the resultant of all forces acting on an object is not equal to zero, leading to acceleration or a change in direction.
Unbalanced Force
Gravity pulls a car downhill with 500 N, while the engine pulls it uphill with 600 N.
What is the Net Force?
100 N Uphill
A rocket launches because exhaust gases push downward, and the rocket moves upward. This is an Example of?
Newton's Third Law
A parked car stays still until someone pushes it. This is an Example of?
Newton's First Law
The motor pushes a boat forward with 150 N, but the current pushes it backward with 100 N and the wind pushes it forward with 20 N.
70 N Forward
A train moves faster when the engine pulls with more power. This is an Example of?
Newton's Second Law
Which law explains why you move forward when a bus suddenly stops?
Newton's First Law (Law of inertia)
If the mass of an object is 50 kg and the acceleration is 2 m/s^2 then what is the Force?
100 Newtons
Which law is considered the law of inertia?
Newton's First Law
What unit do we use to measure Force?
Newtons
What unit do we use to meausre Mass?
kg
A skateboard is speeding down a hill. The skateboard is in ___________? (Fill in the blank)
Motion
