What is a reference point?
Velocity definition?
Speed in a given direction.
If a hockey player puts force into the stick and hits the puck which objects are actions and reactions?
Weight definition?
A measure of the force of gravity acting on an object.
A cross-country athlete runs 4 km in 15 minutes. What can you calculate using this information?
Speed.
Definition of Motion?
When the distance of an object is changed in relation to another object.
Acceleration definition?
The rate at which velocity changes.
Inertia Definition?
The tendency for an object to resist motion.
What factors affect gravity?
Mass, Distance.
Which term describes resistance to change in motion?
Inertia.
When is an object in motion?
When it has gone further away in relation to another object.
How is velocity related to speed and acceleration?
It can control the speed and acceleration depending on the amount of velocity or how fast it changes.
What are action and reaction forces, and how do they impact an object's motion
Action-reaction forces say that when applying force to one object (action) it may affect another object (reaction).
How are gravity and friction related to motion and energy?
Energy determines the motion just like how gravity determines friction.
A soccer player Kicks a ball. Which describes the reaction forces of this kick?
Friction between the ball and the ground.
What is a Newton?
How can you interpret graphs to determine acceleration?
by determining the distance by how long it takes.
How do an object's mass and the forces acting upon an object affect its motion
If the object is heavy it will be harder to move in contrast to a lighter object.
What factors affect the different types of friction?
Mass, Gravity, and Incline.
Give a real-life example of fluid friction.
ANswers may vary.
How do different types of force affect motion?
it changes the direction depending on if its a push or a pull.
How do you determine speed from calculations and distance-versus-time graphs?
Speed equals distance divided by time.
How do Newton's laws of motion describe when and how objects move?
It shows how something needs to be forced upon an object for it to move.
What are the three types of friction?
Static Friction, SLiding Friction, Fluid Friction.
What is the difference between mass and weight?
Mass never changes.
