Acceleration and displacement
what is inertia?
the natural tendency of objects in motion to stay in motion and objects at rest to stay at rest
what is friction?
the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.
what is the definition of acceleration?
The rate of change in velocity.
What is an example of a force that changes the speed of an object?
Example: A soccer player kicking a ball
What is the relationship between force and acceleration?
the net force acting on an object is equal to its mass times its acceleration
What is net force?
When two or more forces act on a object simultaneiously.
what is the speed of a plane going 1500 miles in 8 hours?
what is 187.5 mph
What are the three types of speed?
2. Average
3. constant
What is currently taking place.
