Force
The push or pull of an object
What is Force
the force that pulls falling objects towards Earth
Gravity
Force that opposes motion
What is friction
The measurment used to measure force
What are Newton's
Objects ar rest, stay at rest unless an unbalanced force is applied
What is Newton's 1st law
forces that do not change the motion of an object
What are balanced forces
The force of gravity on a person or object on the surface of a planet
What is weight
Friction when object is in the atmosphere
Air Friction
Rate of change in velocity
What is acceleration
When walking on the beach our foot exerts force on he sand and the sand pushes us forward
What is Newton's 3rd law
The unit of measure of force
What is a Newton
Acceleration of an object is related to force and mass
What is Newton's 2nd law
Resistance that occurs when an object slides over a surface
What is sliding friction
Tendency of a body to remain at rest when force is applied to it
What is inertia
The m in the equation F=ma
What is mass
Marcos pushing against a wall
What is a contact force
Football has a mass of 6kg and travels at an acceleration of 3m²
What is 18N
Resistance that occurs when an object moves through a fluid
What is fluid friction
Speed in a given direction
What is velocity
For every action, there is an equal ad opposite reaction
What is Newton's 3rd Law
Force applied by a person or object that causes movement
What is applied force
Force exerted by a fluid on an object immersed in the fluid
What is buoyancy
Resistance that occurs when an object rests on a surface such as tires on a pavement
Static Friction
The greater the mass of an object, and the faster it moves=greater velocity
What is momentum
Skateboard it hits a curb with the front wheels and you fly off
What is Newton's 1st Law
