我可以直接从Box2D实体获取加速度测量吗？(Python) (Box2D)

import Box2D

# 创建Box2D世界对象
world = Box2D.b2World(gravity=(0, -9.8))

# 创建Box2D实体对象
body_def = Box2D.b2BodyDef()
body_def.type = Box2D.b2_dynamicBody
body_def.position = (0, 0)
body = world.CreateBody(body_def)

# 设置实体的形状和质量等属性
shape = Box2D.b2CircleShape(radius=1.0)
fixture_def = Box2D.b2FixtureDef(shape=shape, density=1.0)
body.CreateFixture(fixture_def)

# 模拟物理效果并更新实体状态
time_step = 1.0 / 60.0
velocity_iterations = 6
position_iterations = 2
for i in range(60):
    world.Step(time_step, velocity_iterations, position_iterations)
    linear_acceleration = body.GetLinearAcceleration()
    print("Linear Acceleration:", linear_acceleration)
