This or that?
Speed vs Velocity
Scalar quantity that defines how fast an object moves regardless of direction
Speed
What is the unit of mass in physics?
Kilograms
What is gravity?
Invisible fundamental force that pulls a mass towards each other.
This means how far something has traveled and it is a scalar
Distance
True of False:
Lightning is a giant version of static electricty
True
Mass vs Weight
Scalar property of matter that remains constant regardless of anywhere in the universe
Mass
What does m/s mean?
meters per second
How goes gravity play a part in rollercoasters?
Gravity pulls the roller coaster down from the top of the hill. This causes it to speed up as it descends, increasing movement.
This term is the change in position of an object
What is friction?
A contact force that opposes the relative/general motion of the attempted motion between two things.
Potential Energy (PE) vs Kinetic Energy (PE)
The energy an object hones due to motion. Depends on the object's mass.
Kinetic Energy (KE)
velocity
What is gravity's acceleration on Earth?
9.81 m/s^S
Term that means "speed with a direction" (magnitude)
Velocity
Static charge
Scalar vs Vector
Quantities defined by numerical values or magnitude, not direction
Scalar
What is the unit of force?
Newtons (N)
What is Newtons Law of Gravitation?
Hint: Its in one of the presentations
F = G (m1)(m2)/r2
The rate at which the velocity is changing
Acceleration
Give a real life example of friction in action
Brushing or rubbing your hair
Energy vs Power
The rate at which work is done or energy is transferred/transformed per unit of time
Power
Unit used for work and energy in physics.
What is the Gravitational Constant?
6.67 x 10^-11 N*m^2/kg^2
What do we call a condition where something is falling under the force of gravity only?
Free fall
True or False:
Wet hair is more static
False, dry hair is
