Easy Vocab
Force
A push or pull that can change the motion of an object
What is friction and how does it affect the motion of an object?
Friction is a force between an object and the surface it is moving over. It affects the motion of an object by decreasing the speed of when the object moves.
Exert
To apply a force
Velocity
Speed in a particular direction
Explain the relationship between force, mass, and velocity.
A force is equal to change in (mass times velocity)
Mass
The amount of matter that makes up an object
What is the correct formula for calculating velocity?
The correct formula for calculating velocity is V=d/t.
What direction do forces need to be exerted to speed up, slow down or change direction?
Sentence starter....
Speed Up: direction its moving
Slow down: opposite direction its moving
Change direction: opposite direction its moving
The same bowling bowl hits 2 pins with different masses. - Explain what happens when they collide, and how the changes in velocity would be different.
The pin with less mass will have a higher change in velocity. The pin with more mass will have a lower change in velocity.
