book on desk, plate on a table, desk on the floor
the formula for SPEED
S = D/T
Definition and example of KINETIC ENERGY
Definition: energy of motion
Ex: exercising,
3 examples of UNBALANCED FORCES
(movement) arrow flying, soccer ball being kicked, car driving down road
X-axis
position with the most potential energy
start and 4
the strength of gravitational attraction between two objects depends on what 2 factors
MASS and DISTANCE
what axis should DISTANCE be graphed on?
Y-axis
position with the most kinetic energy
2
unit that force is measured in
NEWTONS (N)
A box weighs 5 Newtons and is lifted 10 meters. How much WORK was done?
W = F x D
5N x 10m = 50 J
What would increase the POTENTIAL ENERGY of a cart rolling down a ramp?
increasing the HEIGHT or increasing the STEEPNESS
explain in terms of NEWTONS, balanced forces
equal number of forces or Newtons pushing on either side
