Projectile Motion
The two types of motion for projectile motion.
What is horizontal and vertical?
Any force directed toward the center of a circle.
What is centripetal force?
A force that resists motion.
What is friction?
Moving inertia.
What is momentum?
_____________friction is greater than _____________friction.
What is static, kinetic?
True or false: A coin dropped from a cliff will reach the ground before another coin thrown horizontally from the cliff at the same height.
What is false?
When a car turns to the left, why do passengers slide to the right?
What is inertia?
The friction force resisting motion of an object.
What is static friction?
p=_____________
What is mass X velocity?
The MKS units for momentum.
What is kgm/s?
Uniform/constant motion in the horizontal direction is due to an object's __________________
What is inertia?
The symbol for centripetal force
What is Fc
Friction involving objects in motion.
What is kinetic friction?
Mass is the _________part,
Velocity is the ___________ part
What is inertia, motion?
Momentum is a _________________ quantity.
What is vector?
Acceleration of a falling object in the vertical direction is due to________________
What is gravity?
Four variables are involved in circular motion:
What are
1. Radius of circle
2. velocity
3. mass
4. FC , centripetal force
The equal and opposite force to friction force.
What is applied force?
An ______________is needed to change momentum
What is an impulse?
The impulse equation.
What is Force x time = Δ mv?
Satellites are projectiles that fall ____________ the earth.
What is around?
The reason circular motion is accelerated when speed is constant.
What is change of direction?
The equal and opposite force to weight.
What is normal force?
A change in __________ creates an impulse
What is momentum?
_______________ collisions: no net loss of kinetic energy in the system.
________________collisions: two objects stick together when they collide, loss of kinetic energy .
What is elastic, inelastic?
