Is speed a scalar or a vector?

scalar

What direction is the net force on the skateboarder?

up (towards the center)

What force is greater the normal force or the gravitational force? Why?

gravitational force because this is the force directed towards the center of the curved path

What force is causing the centripetal acceleration and centripetal force? *hint: what force is directed towards the center of the circular paht

normal force

T/F: If a car turns at a constant speed there is an acceleration.

true

An object is moving in a COUNTERCLOCKWISE circle at constant speed. What is the direction of the net force at point B?

left (towards the center)

For an object moving in uniform circular motion, does the velocity change?

yes, because the direction is changing

An object is moving in a COUNTERCLOCKWISE circle at constant speed. What is the direction of the acceleration at point B?

left (towards the center)

In uniform circular motion, the velocity is always ___________ to the circular path.

tangent (tangential velocity) or perpendicular

What do you know about the direction of the net force and acceleration?

they are in the same direction, in the case of uniform circular motion they are towards the center of the curved/circular path

Is velocity a scalar or a vector?

vector

Why do you feel an outward force when your in a car and the driver makes a quick turn?

because your body wants to continue with the same speed and the same direction it was going prior to the turn, INERTIA

What is acceleration?

rate of change of velocity

For an object moving in uniform circular motion, does the speed change?

no, because speed does not have a directional component

An object is moving in a COUNTERCLOCKWISE circle at constant speed. What is the direction of the velocity vector at point B?

up

Is acceleration a scalar or a vector?

vector

What force is greater the normal force or the gravitational force? Why?

normal force because this is the force directed towards the center of the curved path
