Velocity, Speed, and Acceleration
Changing speed or direction
What is acceleration?
A 5kg wheelbarrow takes more force to move than a 50kg wheelbarrow
The overall forces acting on an object
What is net force?
Collision where the object move together after impact
What is an inelastic collision?
Attractive and repulsive force between ions
What is electric force?
Acceleration depends on what two factors?
Mass and force
An object's tendency to resist a change in motion
What is inertia?
Collision where the object move in different directions after impact
What is an elastic collision?
Attractive and repulsive force between two poles
What is magnetic force?

What operation do you do when forces are acting in opposite directions?
What is subtraction?
Momentum cannot be created or destroyed
Law of conservation of momentum
Two factors that change the strength of a gravitational force
What is distance and mass?
Find speed.
Distance = 16 m
Time = 4 sec
What is Newton's 3rd Law?
An object moving at the same speed in the same direction
What is balanced?
