When the forces are balanced. It is the same as having no force at all.
Balanced Force
100
An object at rest will remain at rest, and an object in motion will remain in motion unless acted upon by an unbalanced force. What is this and Explain what this means.
Newton's 1st law of motion and answer

A man runs 20 m in 5 sec. What is the man's speed.
4 m/s
100
How do you find speed?
Distance/ Time
200
When an object pushes or pulls another object by touching it.
Contact Force
200
Is force that can change motion. Greater force over powers and moves the object.
Unbalanced Force
200
The Law of Inertia is the resistance of an object to a change in the speed or direction of its motion. What does this mean and what is an example of this?
Car stopping but person still going

Sam starts sliding with a velocity of 1 m/s. After 2 seconds, his velocity is 7 m/s. What is Sam's Acceleration?
3 m/s2
200
How do you find acceleration?
Final V- First V/ Time
300
A force of attraction between two masses.
Gravity
300
Who was the man who formed the theory of gravity and had three laws of motion?
Issac Newton
300
Acceleration of an object increases with increased force and decreases with increased mass, and is in the same direction as the force. What is this and what does this mean?
Newton's Second Law of Motion and answer
300
What is the force needed to accelerate a 20 kg cart 4 m/s2?
80 Newtons
300
How do you find Force?
Mass times Acceleration
400
A force that resists motion between two surfaces that are pressed together.
Friction
400
Any time you change the motion of something you use what?
Force
400
Every action has an equal and opposite reaction. What is this and what does it mean?
Newton's Third Law of Motion and answer
400
If a car pulled with a force of 600 N on a person with a mass of 100 kg. what is the acceleration on the person?
6 m/s2
400
How would you find acceleration if you had force and mass?
Force= Mass times acceleration
Force/ mass = Acceleration
500
The overall force acting on an object when all forces are combined.
Net Force
500
Any force that keeps an object moving in a circle
Centripetal Force
500
What is one law of motion and give me an example of this law shown in real life.
Answer
