Newton’s Laws of Motion Newton’s First Law If there is no unbalanced force an object will move at constant velocity or remain at rest. Newton’s Second.
Newton’s first law states that if the net force acting on an object is zero, the object remains at rest, or if the object is already moving, continues.

Driving Land Vehicle Game Programming Fall 2013

Content Kinematic maneuver Dynamic maneuver

Remark No dynamics Position of vehicle implicitly defined in modelview matrix Difficult to compute bounding boxes

Dynamic Maneuver Assume the vehicle is a particle The power and angle of thrust can be controlled Drag is always opposite to the velocity (no drag is motionless) Integrate equations of motion by Euler’s method thrust = Power Rot (  ) v x drag = -k v  force = thrust + drag

Using Virtual Keyboard UP/Down: increase/decrease power by a ratio Home: start engine with power = 1.0 Space: stop engine with power = 0.0 Left/Right: turning (next page) Force_gas: the thrust force exerted by the power

Engine Force Power: controlled by up, down, home, space Theta_thrust: controlled by tank orientation (theta), left and right

Tank Rendering pos  vel Force_gas x z
